OPINION OF THE COURT
ALITO, Circuit Judge.
This is an appeal from a judgment of civil forfeiture for funds from a bank account owned by Kim’s Wholesale Distributors, Inc. (“Kim’s”). The complaint claimed that the funds were subject to forfeiture under 18 U.S.C. § 981(a)(1)(A) on the ground that they had been involved in transactions in violation of the money laundering statute, 18 U.S.C. § 1956. Proof supporting the forfeiture was obtained from business records seized from [142]*142Kim’s pursuant to a warrant issued by a United States Magistrate Judge in connection with a wide-scale investigation of illegal trafficking in food stamps.
Kim’s moved to suppress the evidence under the Fourth Amendment1 and to dismiss the complaint. When the District Court denied those motions, the parties entered into a stipulation under which Kim’s conceded that it had no defense to the forfeiture action, final judgment was entered against Kim’s in the amount of $92,422.57, and Kim’s retained the right to appeal the District Court’s ruling on its motion to suppress and dismiss. The District Court entered judgment against Kim’s in the amount of $92,422.57, and this appeal followed.2 For the reasons stated below, we reject Kim’s arguments relating to probable cause and particularity, but we find the record inadequate to resolve Kim’s argument concerning the seizure of documents written in Chinese, and we therefore vacate the judgment and remand for further proceedings regarding that issue.
I.
In October 1996, the government received anonymous letters implicating two individuals, Qiang Wang and Qun Chen, in an elaborate food stamp trafficking scheme. According to the letters, Chinese take-out restaurants were buying food stamps from low-income food stamp recipients for seventy cents on the dollar. JA at 107. It was alleged that the restaurants were then reselling the food stamps to a partnership (the “Wang-Chen Partnership”) for ninety cents on the dollar. The partnership, in turn, was allegedly redeeming the food stamps through grocery stores that did little if any legitimate business. Id. The partnership allegedly opened stores, operated them for a time, and then closed them to avoid paying taxes. Id. The letters named three stores, Wyoming Variety Store, Tasker Grocery Store, and Jacky’s Food, that they claimed were operating solely for the purpose of trafficking food stamps. Id.
After receiving the letters, the Secret Service and Department of Agriculture began an extensive investigation. In the spring of 1997, “undercover Secret Service agents sold more than $130,000 in food stamps” to the members of the Wang-Chen Partnership for sixty cents on the dollar.3 Id. at 106. Those food stamps [143]*143were later redeemed through Wyoming Variety, one of the three stores named in the letter, and two others, Gou Bao Grocery and Hing Loong Food Market and Trading, Inc. Id. A sixth store, Zheng’s Grocery, was later identified. Id. at 108. A review of the bank records of five of these six stores revealed that they had “collectively redeemed over $12,000,000 in food stamps since April 1994.” Id. ,
The investigation yielded substantial evidence that these stores did “little if any legitimate retail food business.” Id. at 109. Agents videotaped customer traffic in and out of Gao Bao Grocery and found that on average only eight customers a day left with a bag. The store received few deliveries: a man “carried two to three plastic grocery bags into the store on approximately twenty-one occasions between January and April 1997.” Id. at 137. Yet Gao Bao deposited $1,885,205 in food stamps between September 23, 1996, and May 31, 1997. Id. at 138. The store would have had “to turn over a $5,000 inventory ten times a week to generate these sales.” Id. Wyoming Variety, which had no cash register and was sparsely stocked with a small supply of canned foods and beverages, nevertheless redeemed “$308,359 a month on average” in food stamp deposits. Id. at 140-41. A mail carrier who delivered mail around noon to Jacky’s Grocery reported that the store was closed 85% of the time; nevertheless, between March 6,1995, and March 28, 1996, Jacky’s “deposited $2,735,573 in food stamps,” which “accounted for 99% of all [its] business receipts.” Id. at 147-48.
Tasker Grocery’s mail carrier reported that “the door was always locked.... There were never any customers.” Id. at 150. But Tasker Grocery redeemed $2,004,164 in food stamps between April 1, 1994, and March 22, 1995. Id. Food stamps accounted for 99% of all its deposits. Id.
Officers videotaped Zheng’s Grocery between May 13 and May 16, 1996. The videotape disclosed an employee enter the store at about 8:30 a.m. and lock the door behind him. People who tried to enter the store were unable to do so. The employee left at 4:30 p.m. and locked the door behind him. There were no deliveries. Id. at 152. However, between December 26, 1995, and October 18, 1996, Zheng’s redeemed $2,383,296 in food stamps. Id. Zheng’s deposited only $900 in cash during this entire period. Id. at 153.
The investigation also produced evidence that the sham store owners withdrew food stamp proceeds from their bank accounts [144]*144by checks made payable either to cash, to the store owners, to an employee of a takeout restaurant, or to one of a group of wholesale food companies including Kim’s. Id. at 109, 161. Indeed, all of the sham grocery stores “drafted a substantial number of checks to Kim’s despite the fact that the stores were selling little if any food inventory.” Id. at 161. For example, Zheng’s Grocery drafted $951,603 in checks to Kim’s and Wyoming Variety drafted $46,503 in checks to Kim’s despite doing little legitimate business. Id. at 162. After reviewing canceled checks drafted by sham grocery stores to Kim’s, an agent determined that Kim’s had deposited $399,389.20 from these sources into its account at PNC Bank since September 11, 1996. Id. at 164.
The sham grocery store owners drafted checks to Kim’s in a manner designed to conceal the proceeds of the food stamp trafficking scheme and make it appear that the stores were purchasing significant food inventory. According to the investigating agents, food stamp traffickers mistakenly believe that checks for more than $10,000 result in the filing of a Currency Transaction Report or a Suspicious Activity Report,4 id. at 118, and the vast majority of the checks drafted to Kim’s by Gou Bao Grocery and Zheng’s Grocery were in amounts just below $10,000. Id. 163, 164. Zheng’s Grocery often drafted more than one check a day to Kim’s. For example, on July 1, 1996, Zheng’s drafted four checks to Kim’s in the following amounts: $9,400, $9,300; $9,200, and $9,100. Id. at 163. Gou Bao wrote checks for just under $10,000 several times a week. Id. at 164.
Two lead case agents — Senior Special Agent Debra Thomerson, from the Department of Agriculture, and Special Agent Glen McElravy, from the Secret Service— swore out an affidavit in support of a master search warrant for numerous locations, including Kim’s. Agent Thomerson had been involved in over 100 investigations involving the illegal use of food stamps, had received special training in the area of food stamp trafficking, and was a specialist in the documentation, identification, and retrieval of food stamps. Special Agent McElravy had assisted in numerous money laundering investigations and had received special training in identifying assets subject to forfeiture due to involvement in money laundering offenses. The affidavit underlying the search warrant set forth facts to show that Kim’s was a participant in an ongoing and extensive scheme to traffic in food stamps, in violation of 7 U.S.C. §§ 2024(b) and (c) (food stamp fraud), 18 U.S.C. § 1956 (money laundering), 18 U.S.C. § 1956(h) (money laundering conspiracy), and 18 U.S.C. § 371 (conspiracy). The warrant application was presented to and signed by a Magistrate Judge on September 11, 1997. The warrant authorized the seizure of the following Kim’s records:
1. Receipts, invoices, lists of business associates, delivery schedules, ledgers, financial statements, cash receipt, disbursement, and sales journals, and correspondence.
2. Computers, computer peripherals, related instruction manuals and notes, and software in order to conduct an off-site search for electronic copies of the items listed above.
Id. at 181.
When the warrant was executed, numerous documents were seized from Kim’s premises, including handwritten notes on [145]*145brown paper bags recording food stamp transactions, invoices to Chinese restaurants documenting the exchange of food stamps for Kim’s products at a discount to face value, and an accounting journal cataloging bulk food stamp transactions. Two journals volunteered by an employee revealed bulk food stamp transactions and documented that Kim’s bought food stamps at a discount to face value from at least 19 restaurants in return for wholesale food products, that Kim’s redeemed the food stamps through three grocery stores, and that Kim’s deposited checks from the grocery stores into its bank accounts. See id. at 187-188. Kim’s then sold the illegally obtained food stamps for 90-92 cents to the Wang-Chen Partnership’s sham grocery stores, and the sham grocery stores paid with checks drawn on the stores’ bank accounts. Id. at 35.
II.
A.
Kim’s argues that the District Court erred in refusing to suppress evidence obtained in the search of its premises because the warrant was not supported by probable cause and did not particularly describe the items to be seized. The government counters that the warrant was supported by probable cause and that, in any event, the “good faith” exception to the exclusionary rule, adopted in United States v. Leon, 468 U.S. 897, 104 S.Ct. 3405, 82 L.Ed.2d 677 (1984), applies. Under Leon, if a motion to suppress evidence obtained pursuant to a warrant does not present a Fourth Amendment argument that should be decided in order to provide instruction to law enforcement or to magistrate judges, it is appropriate for a reviewing court to turn “immediately to a consideration of the officers’ good faith.” Id. at 925, 104 S.Ct. 3405. In this case, we do not think that Kim’s probable cause and particularity arguments “involve ... ‘novel questions] of law whose resolution is necessary to guide future action by law enforcement officers and magistrates,’ ” United States v. Satterwhite, 980 F.2d 317, 320 (5th Cir.1992) quoting Illinois v. Gates, 462 U.S. 213, 264, 103 S.Ct. 2317, 76 L.Ed.2d 527 (1983), and we therefore turn directly to the good faith issue. See, e.g., United States v. Taylor, 119 F.3d 625, 629 (8th Cir.1997); United States v. Zayas-Diaz, 95 F.3d 105, 112 (1st Cir.1996); United States v. Cancelmo, 64 F.3d 804, 807 (2d Cir.1995); Satterwhite, 980 F.2d at 320.
B.
Under Leon, suppression of evidence “is inappropriate when an officer executes a search in objectively reasonable rebanee on a warrant’s authority.” United States v. Williams, 3 F.3d 69, 74 (3d Cir.1993). The Supreme Court developed the exclusionary rule to deter unlawful police conduct. Leon, 468 U.S. at 906, 104 S.Ct. 3405. However, where law enforcement officers act in the “objectively reasonable belief that their conduct d[oes] not violate the Fourth Amendment,” “the marginal or nonexistent [deterrent] benefits produced by suppressing evidence obtained in objectively reasonable reliance on a subsequently invalidated search warrant cannot justify the substantial costs of exclusion.” Id. at 918, 922, 104 S.Ct. 3405. Therefore, if an officer has obtained a warrant and executed it in good faith, “there is no police illegality and thus nothing to deter.” Id. at 921, 104 S.Ct. 3405.
To determine the applicability of the good faith exception to the exclusionary rule, we ask “whether a reasonably well trained officer would have known that • the search was illegal despite the magistrate’s authorization.” United States v. [146]*146Loy, 191 F.3d 360, 367 (3d Cir.1999) quoting Leon, 468 U.S. at 922 n. 23, 104 S.Ct. 3405. The fact that an officer executes a search pursuant to a warrant typically “suffices to prove that an officer conducted a search in good faith and justifies application of the good faith exception.” United States v. Hodge, 246 F.3d 301, 308 (3d Cir.2001) citing Leon, 468 U.S. at 922, 104 S.Ct. 3405. Nevertheless, we have identified four narrow situations in which an officer’s reliance on a warrant is not reasonable:
(1) when the magistrate judge issued the warrant in reliance on a deliberately or recklessly false affidavit;
(2) when the magistrate judge abandoned his judicial role and failed to perform his neutral and detached function;
(3) when the warrant was based on an affidavit “so lacking in indicia of probable cause as to render official belief in its existence entirely unreasonable;” or
(4) when the warrant was so facially deficient that it failed to particularize the place to be searched or the things to be seized.
Id. quoting Williams, 3 F.3d at 74 n. 4 (citation omitted).
In the present case, Kim’s does not contend that the affidavit contained deliberately or recklessly false information or that the Magistrate Judge abandoned her judicial role. Instead, Kim’s relies on the third and fourth exceptions noted above and maintains that the affidavit was so lacking in indicia of probable cause and so lacking in the requisite particularity as to render official belief in the warrant’s legality entirely unreasonable. In order to come within these exceptions, Kim’s must show, not just that the Magistrate Judge erred in issuing the search warrant at issue, but that the Magistrate Judge’s error was so obvious that a law enforcement officer, without legal training, should have realized, upon reading the warrant, that it was invalid and should thus have declined to execute it.
III.
Kim’s contends that the affidavit was so lacking in indicia of probable cause that the officers who executed the warrant should have realized that it was invalid. Specifically, Kim’s asserts that “[ajlthough the affidavit to support the search warrant application was detailed with respect to the alleged scheme by the grocery stores and the Chinese restaurants to fraudulently redeem food stamps, it provided almost no information linking those activities to Kim’s.” Appellant’s Brief at 35-35. Kim’s also contends that even if the officers could have reasonably thought that the information in the affidavit provided probable cause that Kim’s premises once contained evidence of the illegal scheme, any reasonable officer should have realized that the information was stale by the time the warrant was issued.
A magistrate judge may find probable cause when, viewing the totality of the circumstances, “there is a fair probability that ... evidence of a crime will be found in a particular place.” Gates, 462 U.S. at 238, 103 S.Ct. 2317. When a warrant is issued and later challenged, a deferential standard of review is applied in determining whether the magistrate judge’s probable cause decision was erroneous. The reviewing court inquires whether there was “a ‘substantial basis’ for finding probable cause,” Hodge, 246 F.3d at 305 quoting United States v. Jones, 994 F.2d 1051, 1054 (3d Cir.1993), as “after-the-fact scrutiny by courts of the sufficiency of an affidavit should not take the form of de novo review.” Gates, 462 U.S. at 236, 103 S.Ct. 2317. “[T]he resolution of [147]*147doubtful or marginal cases in this area should be largely determined by the preference to be accorded to warrants.” Jones, 994 F.2d at 1057-58, quoting United States v. Ventresca, 380 U.S. 102, 109, 85 S.Ct. 741, 13 L.Ed.2d 684 (1965).
We are not persuaded that the affidavit in this case was so deficient in probable cause as to render reliance on it unreasonable. On the contrary, we view the affidavit as making a substantial showing of probable cause on which it was objectively reasonable for the officers to rely. See Hodge, 246 F.3d at 309 citing Williams, 3 F.3d at 74. The affidavit provided great detail regarding a complex food stamp fraud and money laundering scheme that had been extensively investigated by experienced officers. Specifically, the affidavit provided information that the Wang-Chen Partnership was engaged in a multi-million dollar scheme under which the Partnership purchased food stamps at a discount, and redeemed them through “ ‘bogus’ grocery stores.” JA at 107. As noted, undercover agents sold food stamps to the Wang-Chen Partnership, and these stamps were later redeemed by some of these groceries. The investigation showed that these stores did little legitimate business, but a review of the bank records of five of the stores demonstrated that they had collectively redeemed more than $12,000,000 in food stamps since April 1994. Id. at 108. The proceeds from the redemption of the food stamps were withdrawn from the grocery stores’ bank accounts by check, and all of “the grocery stores ... made checks payable to a common set of wholesale food companies,” including Kim’s. Id. at 109, 161. The amount of the checks “far exceeded the value of any food inventory that the stores may have purchased.” Id. at 109.
The affidavit stated that Kim’s received $1,305,302 in payments from these “sham” grocery stores. Id. at 162. These payments could not have been payments for groceries because, as the affidavit clearly sets forth, these stores sold few if any groceries. Therefore, the simple fact that Kim’s cashed checks from grocery stores implicated in the food stamp trafficking scheme is strong evidence that Kim’s was also involved in the scheme. It is therefore apparent that the affidavit “was not a ‘bare bones’ document” and that the officers’ reliance on the search warrant was objectively reasonable. Loy, 191 F.3d at 369.
C.
In arguing that the affidavit in this case was woefully lacking in indicia of probable cause, Kim’s places great weight on the following passage in the affidavit:
[Wholesale food companies that are engaged in food stamp trafficking and money laundering ... maintain records of their legitimate business activity both at their commercial locations and at private residences to which they have access. These records include receipts, invoices, lists of business associates, records of telephone numbers, delivery schedules, ledgers, financial statements, cash receipt, disbursement, and sales journals, and correspondence. This information is relevant because it shows the extent to which the businesses have been engaged in legitimate commerce.
JA at 119 (emphasis added).
Pointing to this passage, Kim’s argues that the “affidavit demonstrate^ that the government was seeking evidence of legitimate business, ... [and] a search warrant should only issue when there is probable cause to believe that ... evidence of a crime will be found in a particular place.” [148]*148Appellant’s Brief at 26 (italics in original). This argument is unpersuasive.
As previously stated, the affidavit provided substantial reason to believe that Kim’s had received large amounts of money from grocery stores that conducted little or no business. This information provided probable cause to believe that Kim’s ordinary books and records would not contain entries showing legitimate grocery purchases by and deliveries to these sham stores, and the absence of such entries would tend to show that the checks issued by these stores to Kim’s were for other than legitimate purposes. We therefore see no problem with this passage in the affidavit, and we hold that there is no ground for suppressing the fruits of the search of Kim’s premises due to lack of probable cause.
D.
Kim’s next argues that suppression is called for because the information in the affidavit relating to Kim’s was stale. The search warrant was executed on September 11, 1997, and the affidavit showed that Kim’s began a relationship with the Wang-Chen Partnership in 1994 and continued to engage in financial transactions with the Partnership through October 25, 1996. JA at 108-09, 162-64. We reject the argument that this 11-month gap rendered the information in the affidavit so clearly stale that reasonable officers could not have believed that the warrant was valid.
Where “an activity is of a protracted and continuous nature, ‘the passage of time becomes less significant.’ ” United States v. Tehfe, 722 F.2d 1114, 1119 (3d Cir.1988) quoting United States v. Johnson, 461 F.2d 285, 287 (10th Cir.1972). Furthermore, where the items to be seized are created for the purpose of preservation, as are business records, the passage of time is also less significant. See United States v. Williams, 124 F.3d 411, 421 (3d Cir.1997). In the present case, as noted, the relationship between Kim’s and the Partnership was of considerable duration, and the warrant authorized a search for standard categories of business records. Businesses typically retain such records for an extended period of time — certainly for more than 11 months. For these reasons, we hold that it was objectively reasonable for the executing officers to believe that the evidence supporting the search warrant was not state.5
IV.
Kim’s contends that the warrant in this case was a “general warrant” and so plainly lacked the requisite particularity concerning the items to be seized that official reliance on it was unreasonable. The Fourth Amendment provides that “no Warrant shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.” The Fourth Amendment does not prohibit searches for long lists of documents or other items provided that there is probable cause for each item on the list and that each item is particularly described.
“The particularity requirement ‘makes general searches ... impossible.’ ” United States v. Christine, 687 F.2d 749, 752 (3d Cir.1982) quoting Marron v. United States, 275 U.S. 192, 196, 48 S.Ct. 74, 72 [149]*149L.Ed. 231 (1927); see also, e.g., Stanford v. Texas, 379 U.S. 476, 480, 85 S.Ct. 506, 13 L.Ed.2d 431 (1965). A general warrant authorizes “a general, exploratory rummaging in a person’s belongings.” Coolidge v. New Hampshire, 403 U.S. 443, 467, 91 S.Ct. 2022, 29 L.Ed.2d 564 (1971). In order for a warrant to be invalidated as general, it must “vest the executing officers with unbridled discretion to conduct an exploratory rummaging through [defendant’s] papers in search of criminal evidence.” Christine, 687 F.2d at 753. As we noted in Christine, examples of general warrants are those authorizing searches for and seizures of such vague categories of items as “ ‘smuggled goods,’ ” “ ‘obscene materials,”’ “‘books, records, pamphlets, cards, receipts, lists, memoranda, pictures, recordings and other written instruments concerning the Communist Party of Texas,’ ” “ ‘illegally obtained films,’ ” and “ ‘stolen property.’ ” Id. (citations omitted).
We have contrasted a “general warrant” with a warrant that is simply overly broad. An overly broad warrant “described] in both specific and inclusive generic terms what is to be seized,” but it authorizes the seizure of items as to which there is no probable cause. Christine, 687 F.2d at 753-54. An overly broad warrant, however, can be cured by redaction, that is, by “striking from [the] warrant those severable phrases and clauses that are invalid for lack of probable cause or generality and preserving those severable phrases and clauses that satisfy the Fourth Amendment.” Id. at 754. Evidence seized pursuant to an overly broad warrant need not be suppressed if the good faith exception applies.
Contrary to Kim’s argument, the warrant here was neither general nor so plainly in violation of the particularity requirement that the executing officers could not have reasonably trusted in its legality. Although the scope of the warrant was certainly extensive, the warrant was not general. The warrant authorized a search for and seizure of the following:
1) Receipts, invoices, lists of business associates, delivery schedules, ledgers, financial statements, cash receipts, disbursement, and sales journals, and correspondence.
2) Computers, computer peripherals, related instruction manuals and notes, and software in order to conduct an off-site search for electronic copies of the items listed above.
JA at 179, 181. The warrant thus “des-cribfed] in ... inclusive generic terms what is to be seized.” Christine, 687 F.2d at 753. It did not vest the executing officers with “unbridled discretion” to search for and seize whatever they wished. Id. It was indubitably broad, but it was not “general.”
Moreover, we think that reasonable officers could have easily believed that the warrant was not even overly broad with respect to the categories of items to be seized. To be sure, the warrant authorized a search for and the seizure of entire categories of legitimate business records, but it is critical to keep in mind that a principal purpose of the warrant was to prove a negative, viz., that Kim’s had not engaged in legitimate business transactions with the sham groceries from which Kim’s had received large cash payments.
The previously quoted passage from the affidavit, which Kim’s attacks, shows why there was probable cause to seize the categories* of business records covered by the warrant. This passage stated:
[Wjholesale food companies that are engaged in food stamp trafficking and [150]*150money laundering ... maintain records of their legitimate business activity both at their commercial locations and at private residences to which they have access. These records include receipts, invoices, lists of business associates, records of telephone numbers, delivery schedules, ledgers, financial statements, cash receipt, disbursement, and sales journals, and correspondence. This information is relevant because it shows the extent to which the businesses have been engaged in legitimate commerce.
JA at 119 (emphasis added). In other words, if Kim’s had engaged in legitimate business transactions with the grocery stores in question — if, for example, it had sold them groceries — its “receipts, invoices, lists of business associates, records of telephone numbers, delivery schedules, ledgers, financial statements, cash receipt, disbursement, and sales journals, and correspondence” would have evidenced such transactions. And if evidence of such legitimate transactions was missing from Kim’s “receipts, invoices, lists of business associates, records of telephone numbers, delivery schedules, ledgers, financial statements, cash receipt, disbursement, and sales journals, and correspondence,” it was reasonable to infer that no such legitimate transactions had occurred. But in order to show that evidence of such transactions was lacking, it was necessary to examine all of Kim’s “receipts, invoices, lists of business associates, records of telephone numbers, delivery schedules, ledgers, financial statements, cash receipt, disbursement, and sales journals, and correspondence” — at least for the relevant period of time. Consequently, a reasonable officer could easily have believed that the breadth of the warrant in this case was justified.6
The dissent contends that the warrant was plainly flawed because it was not “limited ... to documents bearing some relation to Kim’s transactions with the targeted grocery stores or the individuals known to be participants in the fraud” and because it did not specify “the generic types of crimes, i.e., food stamp trafficking or money laundering, to which the items designated for seizure pertained.” Dissent at 27. However, this argument simply overlooks the fact that the investigation in this case sought to prove a negative (that Kim’s had not engaged in legitimate sales to the sham groceries). In order to show that no such sales had occurred, it was necessary to search for and seize all of the files in which a record of such transactions would have been kept. Searching for and seizing only those records that positively showed illicit transactions would not have sufficed. For this reason, it was objectively reasonable for the executing officers in this case to believe that the warrant properly authorized a search for and seizure of the categories of Kim’s business records that the warrant set out.
Kim’s contends that the warrant violated the particularity requirement because it did not restrict the search and [151]*151seizure to documents concerning transactions that occurred during the time period of the illegal food stamp trafficking scheme. In a similar vein, the dissent argues that the warrant, at most, should have covered documents from the period 1994 to 1997 and not for the period 1984 to 1998. Dissent at 26. This argument, however, does not provide a ground for suppressing the evidence supporting the judgment of forfeiture.
The warrant at issue here was tantamount to one authorizing a search for records for the years 1984, 1985, 1986, etc. through 1997. If the dissent is correct that the warrant should not have covered documents from 1984 to 1993, that flaw renders the warrant overly broad, not general. The inclusion of the period from 1984 to 1993 did not “vest the executing officers with unbridled discretion to conduct an exploratory rummaging through [defendant’s] .papers in search of criminal evidence.” Christine, 687 F.2d at 753. Rather, the inclusion of those years simply authorized a search for documents as to which there may not have been probable cause. Under our decision in Christine, the proper remedy for this putative defect was simply to excise the years for which there was no probable cause. At most, the lack of time restrictions meant that the warrant was overly broad, not general. Kim’s could have, but did not, move for redaction of the warrant on this ground. (Redaction is unlikely to have helped Kim’s since one would expect that the documents upon which the government relied to show that bank funds in question were involved in the illegal scheme would fall within the time period of the scheme.) In any event, the absence from the warrant of a provision limiting the search and seizure to documents pertaining to the time period of the scheme did not make the warrant “so facially deficient” “as to render official belief in its [legality] entirely unreasonable.” Hodge, 246 F.3d at 308. Accordingly, the Leon exception to the exclusionary rule precludes suppression of evidence on this ground.
In Massachusetts v. Sheppard, 468 U.S. 981, 104 S.Ct. 3424, 82 L.Ed.2d 737 (1984), the companion case to Leon, the Supreme Court applied the good faith doctrine to a case in which a warrant had been invalidated because it was overly broad. See also United States v. Kepner, 843 F.2d 755, 763 (3d Cir.1988). In Sheppard, the police wished to search the residence of the boyfriend of a murder victim. The supporting affidavit specified that police wanted to search the defendant’s residence for “[a] fifth bottle of amaretto liquor, 2 nickel bags of marijuana, a woman’s jacket that has been described as black-grey (charcoal), possessions of [the victim], similar type wire and rope that match those on the body of [the victim], or in the above [Thunderbird]. [A] [b]lunt instrument that might have been used on the victim. Men’s or women’s clothing that may have blood, gasoline, burns on them. Items that may have fingerprints of the victim.” Id. at, 985, 104 S.Ct. 3424 (quoting the affidavit). The police sought the warrant on a Sunday and were thus unable to obtain the appropriate warrant form. The investigating detective found a warrant form used in another county for searches for controlled substances and brought the warrant to the judge. After reading the affidavit, the judge agreed to authorize the requested warrant and made necessary changes to the controlled substance warrant form in order to tailor it to the case at hand. However, the judge failed to change the directory portion of the warrant, which authorized a search for “any controlled substance, article, implement or other paraphernalia used in, for, or in connection with the unlawful possession or use of any controlled substance.... ” Id. at [152]*152987 n. 2, 104 S.Ct. 3424 (quoting the warrant form). The warrant was thus overly broad.
The Supreme Court held that the Leon exception to the exclusionary rule applies where executing officers reasonably believe that a search is authorized by a warrant that is too broad. The Court observed that a police officer is not required to question a judge who has just advised him that the warrant he possesses authorizes him to conduct the requested search; as the exclusionary rule was developed to “deter unlawful searches by police, [and] not to punish the errors of magistrates and judges,” suppression is inappropriate. Sheppard, 468 U.S. at 990, 104 S.Ct. 3424 quoting Gates, 462 U.S. at 263, 103 S.Ct. 2317 (White, J., concurring in judgment).
The absence of limiting dates in the. warrant in the present case is, at worst, similar to the defect in the warrant in Sheppard. The officers in the present case conducted a lengthy investigation; they reviewed numerous bank transactions; they painstakingly assembled all of the information collected during the investigation, presented it to a neutral and detached Magistrate Judge, and then revised the affidavit and re-presented it to the Magistrate Judge, who found probable cause to issue a warrant.
The members of the Magistrate Judge corps are highly qualified. They are chosen based on merit by the District Court, and competition for Magistrate Judge positions is keen. Magistrate Judges typically have more experience with issues involving warrants than any other judicial officers. The Magistrate Judge in this case believed that the warrant was proper and thus issued it. When a Magistrate Judge has made such a determination, law enforcement officers, who are rarely attorneys, are entitled to rely on the Magistrate Judge’s judgment, except in rare circumstances, such as where the warrant is so plainly defective in form that even a lay officer could not believe in good faith that the warrant was proper. That narrow circumstance is not present here, and we therefore hold that suppression is not justified.

Kim’s final argument is that the officers who executed the warrant violated the Fourth Amendment by seizing all documents written in Chinese, regardless of content, without first determining whether the documents fell within one of the categories specified in the warrant that violated the Fourth Amendment. Kim’s contends that the government should have been required to send a person who was able to read Chinese to the scene of the search in order to determine whether documents written in Chinese fell within the warrant’s scope. Because these arguments raise important Fourth Amendment questions that are not specifically governed by binding precedent, we address the Fourth Amendment issues before turning to the Leon good faith exception. See Leon, 468 U.S. at 925, 104 S.Ct. 3405.
The affidavit in this case explained how the agents planned to deal with the problem of documents written in Chinese. The affidavit stated:
We anticipate that some of the records on the premises to be searched will be recorded in a chínese dialect. The government will attempt to assign an agent who is fluent in at least one chínese dialect to the search teams. It may nonetheless be impossible to screen foreign language documents for relevance on the premises either because they are [153]*153in a dialect unknown to our agents or because we are unable to staff the search location with a chínese speaking agent. We will seize all records that we cannot read. After these records have been reviewed by someone familiar with the dialect used, all records not described in this search warrant shall be returned.
JA at 176-77 (emphasis added). According to the government’s brief, the warrant for the search of Kim’s was one of 23 arrest and search warrants that were executed at the same time by approximately 180 federal and state law enforcement officials, approximately ten of whom spoke Chinese. Appellee’s Br. at 41 n.3. No officer able to speak Chinese was sent to Kim’s. Id. Thus, if the agents who executed the warrant at Kim’s proceeded as stated in the affidavit, they seized all documents written in Chinese. The government represents in its brief that all of the seized documents written in Chinese “fell into one of two categories of documents specified by the warrant: invoices and ledgers,” id. at 40-41, and in view of the scope of the warrant, this may well be true. However, the point is not conceded by Kim’s and the record as it now exists apparently does not show whether or not the government’s representation is true.
The affidavit in this case did not provide probable cause for the seizure of all documents in Chinese, and the warrant did not authorize the seizure of all such documents. This does not mean, however, that the government was necessarily required to send an agent who was able to read Chinese to Kim’s to assist in the execution of the warrant. “The general touchstone of reasonableness which governs Fourth Amendment analysis ... governs the method of execution of the warrant,” United States v. Ramirez, 523 U.S. 65, 71, 118 S.Ct. 992, 140 L.Ed.2d 191 (1998) (citation omitted), and there are plainly circumstances in which it is reasonable to execute a warrant for documents in a foreign language (or for technical records) without the assistance of an officer who is capable of understanding the materials sought. Reasonableness is determined “by assessing, on the one hand, the degree to which [a search or seizure] intrudes upon an individual’s privacy and, on the other, the degree to which [the search or seizure] is needed for the promotion of legitimate governmental interests.” Wyoming v. Houghton, 526 U.S. 295, 300, 119 S.Ct. 1297, 143 L.Ed.2d 408 (1999) (citation omitted). If, for example, there is an urgent need to execute a warrant for documents written in a language that relatively few people in the jurisdiction can read, it may be reasonable to proceed without the assistance of someone able to read the language. If officers were obligated in such a situation to wait until someone who is able to read the language can be found and assigned to assist with the search, vital evidence could be lost, and as we will explain, there are alternative means of minimizing the intrusion on privacy that immediate execution of the warrant would produce. Thus, Kim’s suggestion that an agent who is able to read the language must always be assigned to the team executing the warrant is unreasonable.
At the same, we do not embrace the suggestion that executing officers may always “seize all records that [they] cannot read.” If officers who are able to read the language in question are readily available, the failure to assign such an officer to assist in executing the warrant may be unreasonable. Furthermore, even if there is a sufficient reason not to assign such a person, the warrant must still be executed in a reasonable manner. The privacy of [154]*154those whose Fourth Amendment interests are affected by the search should not be infringed to a greater degree than is reasonably necessary to serve the legitimate interests of law enforcement.
One reasonable way of proceeding is outlined in the Model Code of Pre-Arraignment Procedure § SS 220.5 (1975), which recommends that where “documents to be seized cannot be searched for or identified without examining the contents of other documents, ... the executing officer shall not examine the documents but shall either impound them under appropriate protection where found, or seal and remove them for safekeeping pending further proceedings.... ” Id. at § 220.5(2). Promptly following the removal or im-poundment of the documents, an executing officer should “report the fact and circumstances of the impounding or removal to the issuing official. As soon thereafter as the interests of justice permit, and upon due and reasonable notice to all interested persons, a hearing shall be held before the issuing official ... at which the person from whose possession or control the documents were taken ... may appear ... and move (a) for the return of the documents ... in whole or in part, or (b) for specification of such conditions and limitations on the further search for documents to be seized as may be appropriate to prevent unnecessary or unreasonable invasion of privacy.” Id. at § 220.5(3). This adversary hearing enables the moving party to request that certain procedures be used to “prevent excessive invasions of privacy.” Note to Model Code of Pre-Arraignment Procedure § SS 220.5; see also United States v. Tamura, 694 F.2d 591, 595-97 (9th Cir.1982). These procedures may in-elude conducting the search in the presence of counsel, allowing the moving party to demonstrate that certain files or portions of intermingled documents could not possibly fall within the scope of the search warrant, or requiring that the search be conducted by a special master. See id.
In the present case, the record is insufficient to determine whether the Fourth Amendment was violated as a result of the seizure of documents in Chinese. Although the government’s brief makes representations relating to the need to execute the warrant at Kim’s without assigning an officer able to read Chinese, it does not appear that the present record supports those representations. Moreover, it does not appear that the record reveals whether any documents that did not fall within the scope of the warrant were taken from Kim’s. If no such documents were taken, then there was no violation of the Fourth Amendment. If such documents were taken and retained, there may or may not have been a violation.7 And if there was a violation, there may or may not be grounds for reversing the judgment of forfeiture.
Because of these gaps in the record, we believe that it is advisable to vacate the judgment of forfeiture and remand to the District Court for further proceedings. On remand, Kim’s should identify any documents that were taken in the search and do not fall within any of the categories of documents set out in the warrant. If any such documents are identified, the government should be given the opportunity to establish either that the seizure of these documents was permitted by the Fourth [155]*155Amendment or that the Leon exception to the exclusionary rule precludes suppression.8
VI.
For the reasons explained above, we reject Kim’s arguments relating to probable cause and particularity. However, because of gaps in the present record relating to the seizure of documents written in Chinese, we vacate the judgment of forfeiture and remand to the District Court for further proceedings concerning this issue only.
