UNITED STATES OF AMERICA, No. 23-1677 D.C. No. Plaintiff - Appellee, 3:22-cr-01376-GPC-1 v. MEMORANDUM* STANFORD WALL,
Defendant - Appellant.
Appeal from the United States District Court for the Southern District of California Gonzalo P. Curiel, District Judge, Presiding
Argued & Submitted November 7, 2024 Pasadena, California
Before: CALLAHAN, WALLACH**, and DE ALBA, Circuit Judges.
Defendant-Appellant Stanford Wall appeals his conviction of importing
methamphetamine into the United States from Mexico in violation of 21 U.S.C.
§§ 952 and 960. The parties are familiar with the complete facts, and we
summarize them only as necessary herein. We have jurisdiction pursuant to 28
* This disposition is not appropriate for publication and is not precedent except as provided by Ninth Circuit Rule 36-3. ** The Honorable Evan J. Wallach, United States Circuit Judge for the Federal Circuit, sitting by designation. U.S.C. § 1291. We affirm the conviction.
Mr. Wall was arrested shortly after midnight on June 5, 2022, after Customs
and Border Patrol Officers discovered 23 packages (approximately 20 kilograms)
of methamphetamine hidden in the spare tire mounted to the undercarriage of Mr.
Wall’s vehicle. The sole issue for trial was whether Mr. Wall knew that he was
transporting drugs.
Before trial, the defense moved to exclude expert testimony from Homeland
Security Investigations Special Agent Jamisha Johnson regarding the value of the
drugs found in the tire under Federal Rule of Evidence 403. The district court
granted the motion in part, limiting Agent Johnson’s testimony to the wholesale
value of the drugs. At trial, Agent Johnson testified only as to her qualifications
for expert designation and the approximate wholesale value of the drugs, which she
calculated to be between $41,578.75 and $98,890.
Mr. Wall also sought to cross-examine Agent Johnson about drug
traffickers’ known use of “blind mules” or “unknowing couriers”—individuals that
traffickers use or trick to unknowingly transport drugs into the United States. The
defense proposed a single question: “And you are aware that drug-trafficking
organizations have used unknowing couriers in this district?” The prosecution
responded that if the court allowed the proposed cross-examination, they would
elicit follow-up testimony that Mr. Wall’s case does not resemble known cases
2 23-1677 involving blind mules. The district court acknowledged that blind mules exist, but
excluded the proposed-cross examination under Rule 403, holding that raising the
issue for the first time on cross-examination had “a likelihood of confusing the
issues [and] creating a mini trial on the side.” The court later clarified that its
ruling precluded the defense from asking “any witness, government or otherwise,”
about the existence of blind mules while also allowing Mr. Wall to raise the issue
later as trial unfolded. However, the defense did not raise the blind mule cross-
examination again until its post-trial Rule 33 motion, which the court also denied
because the “idea of blind mules and drug value are not sufficiently related to
permit” cross-examination and because it was “just so general” and too dissimilar
from Mr. Wall’s case.
On appeal, Mr. Wall challenges his conviction on three grounds. First, he
argues the district court failed to conduct the proper Rule 403 balancing test and
improperly admitted Agent Johnson’s drug value testimony. Second, he argues
that precluding his proposed cross-examination about blind mules violated the
Confrontation Clause of the Sixth Amendment. Last, Mr. Wall argues the
prosecutor committed misconduct by raising “facts not in evidence” during closing
arguments. We address each of Mr. Wall’s challenges in turn.
1. Rule 403 permits the exclusion of “relevant evidence if its probative
value is substantially outweighed by a danger of . . . unfair prejudice, confusing the
3 23-1677 issues, [or] misleading the jury.” Fed. R. Evid. 403. Mr. Wall contends that the
district court did not perform the necessary Rule 403 balancing analysis, evidenced
by the fact that there is “no mention in the record of Rule 403.” But district courts
“need not mechanically recite Rule 403’s requirements before admitting evidence.”
United States v. Ono, 918 F.2d 1462, 1465 (9th Cir. 1990) (citations omitted). If it
is “clear from the record that the court implicitly made the necessary finding,” we
review for abuse of discretion. United States v. Ramirez-Jiminez, 967 F.2d 1321,
1326 (9th Cir. 1992) (citations omitted); United States v. Jackson, 84 F.3d 1154,
1159 (9th Cir. 1996) (citations omitted).
Such is the case here, and we find no abuse of discretion. The district court
acknowledged that the drug value testimony is only relevant as circumstantial
evidence of Mr. Wall’s knowledge of the drugs. The record is clear that the district
court considered Mr. Wall’s arguments of undue prejudice, weighed it against the
probative value, and limited Agent Johnson’s testimony to wholesale drug value
only while specifically prohibiting her from testifying about how likely traffickers
are to use blind mules. Mr. Wall contends that the existence of blind mules
necessarily diminished the probative nature of the drug value testimony. But in
this case, the testimony retained its probative value as circumstantial evidence of
knowledge and as a basis for the prosecution to argue that it was not likely
someone would put drugs of that value in Mr. Wall’s car without his knowledge
4 23-1677 given their inability to track or predict his movements.
2. The Sixth Amendment protects the right of the accused “to be
confronted with the witnesses against him” in all criminal cases, which includes
the right to cross-examination. U.S. Const. amend. VI; Davis v. Alaska, 415 U.S.
308, 315 (1974). A Confrontation Clause violation occurs if the defendant was
“prohibited from engaging in otherwise appropriate cross-examination designed to
show a prototypical form of bias on the part of the witness.” Delaware v. Van
Arsdall, 475 U.S. 673, 680 (1986). We, like the Supreme Court, have “emphasized
the policy favoring expansive witness cross-examination in criminal trials.”
United States v. Larson, 495 F.3d 1094, 1102 (9th Cir. 2007) (en banc) (quotation
marks omitted) (citing cases). However, while the Confrontation Clause
“guarantees an opportunity for effective cross-examination,” it does not require
courts to allow “cross-examination that is effective in whatever way, and to
whatever extent, the defense might wish.” Van Arsdall, 475 U.S. at 679. Trial
courts “retain wide latitude . . .

2. The Sixth Amendment protects the right of the accused “to be
confronted with the witnesses against him” in all criminal cases, which includes
the right to cross-examination. U.S. Const. amend. VI; Davis v. Alaska, 415 U.S.
308, 315 (1974). A Confrontation Clause violation occurs if the defendant was
“prohibited from engaging in otherwise appropriate cross-examination designed to
show a prototypical form of bias on the part of the witness.” Delaware v. Van
Arsdall, 475 U.S. 673, 680 (1986). We, like the Supreme Court, have “emphasized
the policy favoring expansive witness cross-examination in criminal trials.”
United States v. Larson, 495 F.3d 1094, 1102 (9th Cir. 2007) (en banc) (quotation
marks omitted) (citing cases). However, while the Confrontation Clause
“guarantees an opportunity for effective cross-examination,” it does not require
courts to allow “cross-examination that is effective in whatever way, and to
whatever extent, the defense might wish.” Van Arsdall, 475 U.S. at 679. Trial
courts “retain wide latitude . . . to impose reasonable limits on [] cross-examination
based on concerns about, among other things, harassment, prejudice, confusion of
the issues . . . or [marginally relevant] interrogation.” Larson, 495 F.3d at 1101
(quoting Van Arsdall, 475 U.S. at 679). And this court has stated that “[a]
limitation on cross-examination does not violate the Confrontation Clause unless it
limits relevant testimony and prejudices the defendant, and denies the jury
5 23-1677 sufficient information to appraise the biases and motivations of the witness.” Id. at
1103 (quoting United States v. Holler, 411 F.3d 1061, 1065 (9th Cir. 2005)
(emphasis added) (internal quotation marks omitted)); accord. United States v.
Urena, 659 F.3d 903, 907–08 (9th Cir. 2011).
We review de novo a “Confrontation Clause challenge based on the
exclusion of an area of inquiry.” Larson, 495 F.3d at 1101 (clarifying the standard
of review). We consider three factors to determine if a Confrontation Clause
violation occurred: (1) whether the excluded evidence was relevant; (2) whether
there were other legitimate interests outweighing the defendant’s interest in
presenting the evidence; and (3) whether the exclusion of evidence left the jury
with sufficient information to assess the witness’s credibility. Id. at 1103 (cleaned
up) (quoting United States v. Beardslee, 197 F.3d 378, 383 (9th Cir. 1999)).
It appears undisputed that the blind mule inquiry is relevant to Mr. Wall’s
case in the sense that it tends to make it more probable that he did not know about
the drugs. See Fed. R. Evid. 401; United States v. James, 139 F.3d 709, 713 (9th
Cir. 1998) (analyzing the relevance prong under Rule 401 standards). Mr. Wall’s
knowledge was the only issue for trial, and knowledge is an element of the crime.
See 21 U.S.C. § 960(a). We conclude that the first factor tips in Mr. Wall’s favor.
The second factor is close, but tips slightly in favor of the Government. We
begin by “considering the probative value of the evidence.” Larson, 495 F.3d at
6 23-1677 1104 (citation omitted). The mere fact that drug traffickers use blind mules is only
marginally probative of Mr. Wall’s knowledge in this case. Mr. Wall’s proposed
question, “And you are aware that drug-trafficking organizations have used [blind
mules] in this district,” says nothing about Mr. Wall’s circumstances or his trip to
Mexico on June 4, 2022. Moreover, even if the defense had asked its single
question on cross-examination, the jury would have then immediately heard how
Mr. Wall does not match the known characteristics of blind mules on re-direct
examination. Therefore, while the district court somewhat overestimated the risk
of jury confusion, a “mini-trial,” or a prolonged discussion about blind mules, the
risk still outweighed Mr. Wall’s minimal interest in the proposed cross-
examination on the facts of this case.
The third factor weighs decisively against Mr. Wall. Agent Johnson testified
only to her qualifications and the approximate wholesale value of the drugs found
in the spare tire. Cross-examining her about drug traffickers’ use of blind mules
simply has nothing to do with her credibility or any “prototypical form of bias”
that the Confrontation Clause ensures an opportunity to present. Van Arsdall, 475
U.S. at 679. Mr. Wall is correct that the existence of blind mules attacks the
underlying purpose and the implication of knowledge that drug value testimony
brings in importation cases, but he fails to explain how it has anything to do with
Agent Johnson’s reliability or credibility in this case such that he has a
7 23-1677 constitutional right to cross-examination about blind mules.
Mr. Wall does not cite any case finding a Confrontation Clause violation
where there was no limitation on the defendant’s ability to ask questions regarding
the witness’s credibility. We have also declined to find a Confrontation Clause
violation where, as here, a defendant is permitted to cross-examine a witness on
issues testified to on direct, as well as on matters of bias and motivation. See
Urena, 659 F.3d at 907–08.
We therefore find no Confrontation Clause violation under the
circumstances of this case.
3. Finally, we address Mr. Wall’s claim of prosecutorial misconduct.
Our case law is split on whether the de novo or abuse of discretion review
standards apply. See United States v. Velazquez, 1 F.4th 1132, 1136–37 (9th Cir.
2021). We need not decide the issue, however, as Mr. Wall’s claim fails under
either standard. The “relevant question is whether the prosecutors’ comments ‘so
infected the trial with unfairness as to make the resulting conviction a denial of due
process.’” Darden v. Wainwright, 477 U.S. 168, 181–82 (1986) (citation omitted).
Mr. Wall challenges the following statements made during closing
argument, specifically in rebuttal:
[Prosecutor:] And agent Fitch fairly characterized, “I didn’t see evidence of drug trafficking on his phone.” But as she also said, phone calls don’t say, “drug-trafficking phone call.” Phone calls to say [sic], “Hey, I am here. Hey the car is there” –
8 23-1677 [Defense Attorney]: Objection. Facts not in evidence.
The Court: Ultimately, the jury, as the trier of fact, determines what the facts are. You recall the evidence, and the objection is overruled. You may proceed.
[Prosecutor]: I will word that differently. Phone records showing a call took place do not say whether that call was related to drug trafficking. So records of phone calls, on their own, are what -- wouldn’t show anything to Agent Fitch, so don’t read too much into that.
Mr. Wall maintains that the statements about the cell phone records
improperly refer to “facts not in evidence.” The record does not support Mr.
Wall’s characterization of the prosecutor’s statements. Prosecutors may base their
closing argument on evidence submitted at trial and may “suggest that the jury
draw reasonable inferences from the evidence presented at trial.” United States v.
Flores, 802 F.3d 1028, 1035 (9th Cir. 2015); see also United States v. Hermanek,
289 F.3d 1076, 1100–01 (9th Cir. 2002); United States v. Cabrera, 201 F.3d 1243,
1250 (9th Cir. 2000). That is all the prosecutor did here. The prosecutor closely
paraphrased Agent Fitch’s actual testimony that she did not find evidence of drug
trafficking in the cell phone records, but also that those records alone do not show
the content of calls or indicate that any calls are about drug trafficking. We find no
misconduct.
Mr. Wall’s conviction under 21 U.S.C. §§ 952 and 960 is AFFIRMED.
