Unpublished opinions are not binding precedent in this circuit. WILKINSON, Circuit Judge:
Defendant-appellant Marion Campbell was charged with possession of
methamphetamine with intent to distribute, possession of a firearm in furtherance of drug
trafficking, and possession of a firearm as a convicted felon. After a jury trial, he was
convicted on all three counts. On appeal, Campbell brings two claims. First, he argues
that the recorded jail calls that were admitted at trial violated Federal Rule of Evidence
404(b). Second, he argues that DEA Agent Todd Briggs did not sufficiently establish his
methodology for his expert testimony under Rule 702. For the reasons that follow, we
affirm the judgment of the district court.
I.
On July 8, 2017, Campbell was pulled over by two Walterboro police for driving
with an inoperative headlight. When dispatch informed the officers that the defendant had
a suspended license, they arrested him and had a K9 sniff his vehicle. After the dog alerted
the officers to the presence of narcotics, they searched the vehicle and found a loaded
handgun, ammunition, a bag of methamphetamine, a small bag of crack cocaine, small
amounts of marijuana, and empty small plastic baggies.
Campbell was indicted on three counts: (1) possession of meth with intent to
distribute in violation of 21 U.S.C. § 841(a)(1), (b)(1)(C); (2) possession of a firearm in
furtherance of drug trafficking in violation of 18 U.S.C. § 924(c)(1)(A)(i); and (3)
possession of a firearm as a felon in violation of 18 U.S.C. §§ 922(g)(1), 924(a)(2), (e).
While in custody pending trial, he made hundreds of phone calls that were recorded. The
district court admitted two calls (Call #8 and Call #11) at trial over the defendant’s
2 objections. The court found that Call #8 was “admissible to show consciousness of guilt
and knowledge by the defendant on how to make meth.” J.A. 366. And Call #11 was
admissible “to prove intent” to distribute drugs. J.A. 370.
In Call #8, Campbell told his ex-girlfriend, Lee Guess, that he had been “getting it
for . . . three hundred a half.” J.A. 191. Guess referred to the product as “clear” and said
she could get it for four hundred, which Campbell said was “a good price.” J.A. 191.
Campbell told her not to get diluted ammonia when she goes to Ace Hardware. J.A. 192.
Guess responded by reminding Campbell not to “say[] this over this phone.” J.A. 192.
Campbell said that the “pure ammonia” was for their “cleaning business.” J.A. 192–93.
Call #11 was also between Campbell and Guess. He requested that she ask another
person about the quality of “clear” that he had been selling. J.A. 199. He told her that his
product had “[n]o shake” and “didn’t crumble” when broken up. J.A. 199.
These two calls were explained at trial by the government’s expert witness, retired
DEA Special Agent Todd Briggs. Briggs retired from the DEA after twenty years of
service. Before that, he was a Marine Corps infantry officer whose last assignment was
conducting counter drug operations at the U.S.-Mexico border. During his DEA service,
Briggs spent ten years in Iowa “work[ing] almost exclusively methamphetamine cases.”
J.A. 475. He then relocated to Columbia, South Carolina, where he worked cocaine,
marijuana, methamphetamine, and opioid cases. He had formal training at the DEA
Academy on “everything from drug identification, how drug operations work, . . . the
history of the illegal drug trade in [the] United States” and later at a series of specialized
schools to learn how to handle specific situations such as clandestine laboratories. J.A.
3 476. He also learned on the job by reviewing telecommunications, such as phones and
pagers. He interviewed over one hundred drug traffickers and listened to hundreds of hours
of surveillance—in 2007 alone, Briggs conducted “nine months of surveillance in one
town.” J.A. 477. During his career, he listened to real-time telephone calls through court-
approved wiretaps of traffickers’ phones in eight- or ten-hour shifts.
After Briggs explained his credentials and his work experience, the defendant
objected to Briggs testifying about the intent of the defendant. The government explained
that Briggs was not there to testify as to intent but rather as to the meaning of Campbell’s
coded drug language and how the meth trade operates. The court cautioned Briggs not to
say anything suggesting he knew of the defendant’s actual intent, and then admitted him
as an expert witness. J.A. 481–82. Briggs proceeded to explain the nature, manufacture,
and distribution of meth, the slang terms and code words for meth, and both the drug market
generally and the South Carolina meth market specifically. See J.A. 483–99. He also
explained the language used on the recorded calls. See J.A. 488–92.
The jury returned a guilty verdict on all three counts of the indictment. The
defendant was sentenced to 360 months’ imprisonment. This appeal timely followed.
II.
Campbell first argues that the recorded jail calls were overly prejudicial evidence
that should not have been admitted pursuant to Federal Rule of Evidence 404(b). We
review the trial court’s ruling as to the admissibility of evidence for abuse of discretion.
United States v. Day, 700 F.3d 713, 728 (4th Cir. 2012). Upon examining the record, we
find none.
4 Rule 404(b) divides “other crimes, wrongs, or acts” into two categories. It prohibits
admission of evidence of such “to prove a person’s character in order to show that on a
particular occasion the person acted in accordance with the character.” Fed. R. Evid.
404(b)(1). However, it allows such evidence to “prov[e] motive, opportunity, intent,
preparation, plan, knowledge, identity, absence of mistake, or lack of accident.” Fed. R.
Evid. 404(b)(2). This rule “is an inclusive rule, admitting all evidence of other crimes or
acts except that which tends to prove only criminal disposition.” United States v. Lespier,
725 F.3d 437, 448 (4th Cir. 2013) (quoting United States v. Rooks, 596 F.3d 204, 211 (4th
Cir. 2010)).
We have developed a four-part test to assess the admissibility of evidence under
Rule 404(b):
(1) The evidence must be relevant to an issue, such as an element of an offense, and must not be offered to establish the general character of the defendant. (2) The act must be necessary in the sense that it is probative of an essential claim or an element of the offense. (3) The evidence must be reliable. And (4) the evidence’s probative value must not be substantially outweighed by confusion or unfair prejudice in the sense that it tends to subordinate reason to emotion in the factfinding process.
United States v. Bell, 901 F.3d 455, 465 (4th Cir. 2018) (quoting United States v. Queen,
132 F.3d 991, 997 (4th Cir. 1997)). Failing the fourth prong requires more than the
evidence be damaging to the defendant’s case because “highly probative [evidence]
invariably will be prejudicial to the defense.” Id. (quoting United States v. Basham, 561
F.3d 302, 326 (4th Cir. 2009)) (alteration in original).
5 The two phone calls admitted at trial meet the requirements of this test. First,
Campbell’s discussion of the market price for meth, an ingredient for meth, and meth
quality speaks to his knowledge and intent, which are two legitimate reasons for admitting
this kind of evidence. See Fed. R. Evid. 404(b)(2). They show that the defendant charged
with trafficking meth was knowledgeable about the business of manufacturing and
distributing meth. Since he was the only person in the stopped vehicle, this was highly
probative of his state of mind. Since Campbell’s intent was at issue as an element of the
offense, this evidence also satisfied the second part of the test. Third, the evidence was
reliable because the words were the defendant’s own. Finally, there was nothing
particularly emotional about this evidence that might subordinate the faculties of reason,
so there was no unfair prejudice. Any risk of such prejudice was mitigated by the district
court’s limiting instruction. See Lespier, 725 F.3d at 448 (citing United States v. White,
405 F.3d 208, 213 (4th Cir. 2005)); J.A. 607–08.
Ultimately, this issue presents a question of the weight of the evidence, not a
question of admissibility. Defense counsel was free to explore that weight on cross-
examination. And the jury was free to assign whatever weight it found appropriate to the
evidence in reaching its verdict. As such, the district court did not abuse its discretion in
admitting the phone calls.
III.
Campbell’s second assignment of error is that the district court improperly admitted
Agent Briggs as an expert witness. He argues that the government failed to establish
6 Briggs’s methodology in deciphering the drug lingo on the calls. We review this ruling for
abuse of discretion. United States v. Chikvashvili, 859 F.3d 285, 292 (4th Cir. 2017).
If an error is harmless, we will not vacate the conviction. United States v.
Sutherland, 921 F.3d 421, 429 (4th Cir. 2019); see also Fed. R. Crim. P. 52(a) (“Any error,
defect, irregularity, or variance that does not affect substantial rights must be
disregarded.”). An error is harmless when the court is able to conclude, after reviewing
the record as a whole, “that the judgment was not substantially swayed by the error.”
United States v. Johnson, 587 F.3d 625, 637 (4th Cir. 2009) (quoting Kotteakos v. United
States, 328 U.S. 750, 765 (1946)). When it comes to evidentiary rulings, we do not reverse
“for inconsequential technicalities. Rather, ‘reversal is reserved for more serious errors
that affect substantial rights or that directly affect the outcome of a case.’” United States
v. Briley, 770 F.3d 267, 276 (4th Cir. 2014) (quoting United States v. Ferguson, 752 F.3d
613, 619 (4th Cir. 2014)). “Where, as here, the error was preserved,” the government bears
the burden of proving harmlessness. United States v. Hedgepeth, 418 F.3d 411, 419 (4th
Cir. 2005).
A.
Assuming arguendo that the failure to explain that the methodology here was error,
we think that the government has demonstrated that the error was harmless. First and
foremost, there was ample other evidence introduced at trial for a reasonable jury to convict
the defendant. To convict a person of possession with intent to distribute a controlled
substance under 21 U.S.C. § 841(a)(1), “the government must prove: (1) possession of a
narcotic controlled substance; (2) knowledge of the possession; and (3) the intent to
7 distribute.” United States v. Collins, 412 F.3d 515, 519 (4th Cir. 2005) (citing United States
v. Randall, 171 F.3d 195, 209 (4th Cir. 1999)).
Possession can be established by either actual or constructive possession. United
States v. Herder, 594 F.3d 352, 358 (4th Cir. 2010). “A person may have
constructive possession of contraband if he has ownership, dominion, or control over the
contraband or the . . . vehicle in which the contraband was concealed.” Id. (citing United
States v. Armstrong, 187 F.3d 392, 395 (4th Cir. 1999)). Like the defendant in Herder,
Campbell was the only person in the car with the meth and the drugs were within his reach;
thus he had such dominion and control to establish possession. See id. at 358–59. Not
only was the meth within Campbell’s reach, it was in his door—a location of easy access
and visibility. A reasonable jury could infer knowledge from this information. See, e.g.,
United States v. Mendoza¸ 522 F.3d 482, 489 (5th Cir. 2008). Finally, the baggies found
in the car support an intent to distribute. See, e.g., United States v. Dennison, 925 F.3d
185, 189 (4th Cir. 2019) (discussing drug paraphernalia that can support a finding of intent
to distribute). In sum, there was sufficient evidence from Campbell’s vehicle to support
his § 841 conviction.
The same logic applies to defendant’s gun convictions. The gun was found
underneath the driver’s seat with .38 rounds on the driver’s floorboard. For the reasons
articulated above, that fact can support the jury’s finding of possession on both gun
charges. And possessing a gun in close proximity to narcotics is sufficient for a § 924(c)
possession in furtherance of drug trafficking conviction. See, e.g., United States v. Lomax,
8 293 F.3d 701, 704–06 (4th Cir. 2002). Thus, a reasonable jury could have convicted
Campbell on the gun charges based on the evidence from his vehicle as well.
B.
With regard to the expert testimony itself, it is conceded that Briggs had the
necessary relevant experience to draw the conclusions he presented. Federal Rule of
Evidence 702 provides:
A witness who is qualified as an expert by knowledge, skill, experience, training, or education may testify in the form of an opinion or otherwise if: (a) the expert’s scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue; (b) the testimony is based on sufficient facts or data; (c) the testimony is the product of reliable principles and methods; and (d) the expert has reliably applied the principles and methods to the facts of the case.
However, not all experts are the same, and courts can treat, say, a product engineer in a tort
case differently from a scientist or a drug expert. See, e.g., Kumho Tire Co. v. Carmichael,
526 U.S. 137, 141–42 (1999) (explaining that district courts have “broad latitude” in “how
to determine reliability” such that engineers can be evaluated differently from scientists,
id. at 142 (emphasis omitted)).
In narcotics cases, we have long held that expert testimony on the meaning of coded
language and drug trafficking patterns by government agents with field experience is
admissible. In fact, in United States v. Wilson, 484 F.3d 267 (4th Cir. 2007), we rejected
an argument very similar to the defendant’s here. See id. at 273–74 (“The thrust of
Appellants’ argument is that [Agent] Seabolt failed to explain adequately how his
experience in the narcotics field supported the methodology used and the ultimate
conclusions made concerning the coded language spoken in the recorded conversations.”).
9 We explained that “[e]xperiential expert testimony” was different from scientific expert
testimony and was allowable from “law enforcement officers with extensive drug
experience.” Id. at 274–75. The advisory committee notes specifically considered this
kind of testimony. See id. (“[T]he principle used by the agent is that participants in such
transactions regularly use code words to conceal the nature of their activities. The method
used by the agent is the application of extensive experience to analyze the meaning of the
conversations.” (quoting Fed. R. Evid. 702 advisory committee’s note)). In numerous
cases, we have allowed this testimony from law enforcement. See, e.g., United States v.
Smith, 919 F.3d 825, 835–36 (4th Cir. 2019) (allowing FBI agent with “substantial
experience in drug and gang investigations” to decipher drug conversations, id. at 835);
United States v. Garcia, 752 F.3d 382, 389–91 (4th Cir. 2014) (finding that FBI agent was
properly admitted as an expert to decode drug slang in conversations); United States v.
Hopkins, 310 F.3d 145, 150–51 (4th Cir. 2002) (allowing “expert testimony by
[Montgomery County] police officer Lawrence Phillips regarding narcotics trafficking,”
id. at 150).
Agent Briggs is no different than the countless other government agents qualified
to give expert opinions on the meaning of coded drug lingo and the functioning of drug
trafficking operations. And he documented his qualifications for the court and jury—year
upon year of experience investigating drug operations. From that experience, we can
deduce his methodology. He had heard the language used, seen the trafficking transpire,
interviewed drug operatives, and pieced together the meaning of the street slang. See
10 Wilson, 484 F.3d at 275 (approving an agent who employed such a method). He then
applied that knowledge to Campbell’s recorded conversations. See J.A. 494–96.
As to the drug pricing, Briggs had worked drug distribution cases in South Carolina
long enough to know typical going rates for bulk purchases of meth—much like commuters
might be attuned to fluctuations in gas prices along their regular route. He explained how
drug prices vary like many other products based on quantity purchased. See J.A. 486–87.
And he also explained that the prices discussed in the call were consistent with the prices
at which he saw meth being sold in South Carolina at the time Campbell was arrested. See
J.A. 489, 498–99.
Agent Briggs further testified as to the use of ammonia in the meth manufacturing
process. See J.A. 490–91. Although he did not talk about his methodology here, he earlier
said that he had attended DEA classes on “how drug operations work” and on “clandestine
laborator[ies].” J.A. 476. His experience as a practicing DEA agent surveilling meth
traffickers and manufacturers would have provided him with a basis for knowing how
manufacturers procure the ingredients and why different people procure each ingredient.
See J.A. 491. His testimony derived from his prior study of meth manufacturing as a part
of his DEA training and his observation of manufacturing while working as an agent.
Furthermore, Agent Briggs was open to cross-examination. Campbell’s attorney
asked him about his involvement in this particular case, to which Briggs responded that he
had none, other than listening to the recorded jail calls. J.A. 499–500, 503–04. When
questioned about the ammonia discussed in one of the jail calls, he explained the difference
between the pure ammonia needed for the production of meth and the diluted ammonia
11 available at hardware stores. See J.A. 504–06. Finally, he explained that “shake” could
refer to marijuana in addition to meth. J.A. 507. At no point was this cross-examination
curtailed and the defendant does not contend that it was.
It is true that Agent Briggs did not point to a specific experience to inform each
opinion, but we have never required this for experiential expert opinions. See Smith, 919
F.3d at 836. This is because the application of “years of investigatory experience and
exposure to thousands of gang and drug conversations . . . to analyze the meaning of certain
terms does not lend itself to a direct correlation between one experience and opinion.” Id.
Given the relevance of the expert’s experience, the cross-examination of the expert, and
the substantial evidence independent of the expert testimony, we find that any error
pertaining to an insufficient explanation of methodology was harmless.
IV.
For the foregoing reasons, we affirm the judgment of the district court.
AFFIRMED
12 WYNN, Circuit Judge, concurring in the judgment:
I concur in the outcome reached by majority opinion. I write separately to emphasize
that while the district court’s admission of Special Agent Briggs’s testimony on drug slang
was harmless error, it was nonetheless error.
In United States v. Wilson, our chief case on the admissibility of law enforcement
testimony to contextualize and explain drug lingo, 1 we considered whether a district court
erred by admitting the expert testimony of a law enforcement officer who, at times, “offered
his interpretation of the meaning of a conversation without offering any reliable
explanation as to why he opined that the conversation meant what it did.” 484 F.3d 267,
276 (4th Cir. 2007). We concluded that while the officer “applied his methods and
principles reliably in the vast majority of his testimony,” the district court “erred in failing
to exclude [his] testimony when . . . [he] did not adequately explain his methodology in
reaching a questionable interpretation.” Id. at 277–78.
1 The Federal Rules of Evidence assumes that players in drug transactions use coded language “to conceal the nature of their activities.” Fed. R. Evid. 702 advisory committee’s notes to 2000 amendments. Our precedent largely adopts this assumption. See, e.g., Wilson, 484 F.3d at 276 (asserting that “the primary purpose of coded language is to conceal the meaning of the conversation from outsiders through deliberate obscurity” (quoting United States v. Gibbs, 190 F.3d 188, 211 (3d Cir. 1999))). But as with many of the assumptions that underpin our practice of permitting law enforcement agents to testify as expert witnesses on the communications of drug dealers, this assumption may lack a solid empirical foundation. My own suspicion is that much drug slang and lingo and even “code” may simply be the product of a culture where miscommunication and misinterpretation can trigger far greater consequences than arrest, and where particularly precise communication is therefore necessary. I believe district courts should be similarly precise in identifying why drug dealers depart from “the King’s English” before they determine whether a proposed expert witness may properly testify regarding the communications at issue.
13 Here, Special Agent Briggs offered virtually no explanation of his methodology or
of how he applied his method reliably to the facts of this case to determine the meaning of
non-self-evident terms or phrases like “clear,” “shake,” “crumble,” and “ears were
ringing.” J.A. 489, 492. The district court therefore erred in failing to exclude this
testimony. See Wilson, 484 F.3d at 278; United States v. Johnson, 617 F.3d 286, 294–95
(4th Cir. 2010) (expressing doubt that an officer’s testimony would have been admissible
to explain drug lingo under Rule 702 when the officer “repeatedly indicated that he had the
expertise to testify regarding drug jargon and the drug trade generally, [but] provided
virtually no methodology or guiding principles that would enable him to decode the
wiretapped phone calls [at issue]”).
But for the reasons ably described by my good colleague, this error was harmless. I
therefore vote to affirm.
