dissenting:
I respectfully dissent from the majority’s holding reversing the district court. There was only one error that occurred in this case, and it was harmless.
I.
The district court did not err by allowing the government to solicit the agent’s opinion regarding the credibility and guilt of Alvarado. Though the questioning may have elicited improper expert testimony, the subject matter of the questioning was relevant to issues the defense had raised in opening argument: that the agents called Alvarado a liar to bully him into confessing. The defense “opened the door” to the question of whether and why government agents said they did not believe Alvarado, and so it was not improper for the court to allow rebuttal testimony. United States v. Beck, 418 F.3d 1008, 1016 (9th Cir.2005).
Although the agent in this case may have presented opinions on habit and behavior, and as such should have been properly qualified “as having the knowledge, experience, training, or education” to serve as an expert witness, United States v. Figueroa-Lopez, 125 F.3d 1241, 1245, any error was harmless. Even though the agent was not subjected to formal qualifying procedures, he did, in fact, have extensive experience, which was introduced into the record:
*689Q: In your experience, I think counsel went over the fact that you’ve had hundreds of cases involving smuggling and things of that nature, you’re an experienced agent?
A: Yes, sir.
Q: So my question is, in your experience, is it unusual for a person you suspect of smuggling drugs to initially deny but later change their story and admit knowledge of the drugs in the vehicle?
[defense counsel]: Objection, your honor, structure.
The court: Overruled.
A: It’s absolutely not uncommon for it to go from initial denial to admitting to what happened.
[defense counsel]: In addition, calls for expert testimony, Rule 16, move to strike.
Given his experience, the agent was likely qualified to give “an expert opinion on modus operandi, ” Figueroa, 125 F.3d at 1247 (quoting United States v. Maher, 645 F.2d 780 (9th Cir.1981)). It is far from clear that the verdict would have been different had the government complied with the evidentiary rules. See Figueroa, 125 F.3d at 1247.
II.
The district court did not err in allowing the government to elicit and argue evidence of poverty, because the admitted evidence tended to show desperation, not mere poverty, and thus its probative value outweighed the possibility of prejudice. In determining whether a district court erred in admitting evidence of a defendant’s poverty, “it is necessary to consider the facts of the particular case.” United States v. Mitchell, 172 F.3d 1104, 1108 (9th Cir. 1999). Thus, no blanket rule applies, but evidence of poverty offered for motive must generally demonstrate “more than the mere fact that the defendant is poor.” United States v. Jackson, 882 F.2d 1444, 1449 (9th Cir.1989). Poverty evidence must show either an abrupt shift in circumstances for the better (such as a sudden wealth of quarters the day after a laundromat robbery), or desperation (such as a sudden necessity to pay off massive debts). Mitchell, 172 F.3d at 1108.
Here the government’s evidence tended to show desperation, not the mere fact of poverty. The evidence tended to show Alvarado was “squeezed, not just poor.” Mitchell, 172 F.3d at 1109. Evidence was introduced that tended to show Alvarado had new hospital bills to pay for his mother, and that he had recently become unemployed. This evidence shows a sudden need, and is thus probative of desperation. Furthermore, unlike in cases such as Mitchell where evidence was introduced of the defendant’s poverty as a general matter, the evidence here was specific and context-bound, without touching on Alvarado’s general financial circumstances. As such, the district court did not abuse its discretion in admitting the evidence.
III.
It was not an abuse of discretion for the district court to overrule the defense’s objection, based on Federal Rule of Evidence 403, to certain government questions relating to individuals on television.
You hear stories all the time about people, who you wouldn’t even think would drive drugs across the border, were caught bringing drugs across the border.
You’ve heard of that, living in this country for 25 years.
I’m sure you’ve heard, in a lot of those cases, where people admit that they did it.
*690You’re aware that people who are caught — these people who you would never think would be involved in a drug smuggling venture, have been found guilty of that, correct?
This line of questioning resulted in only one answer by Alvarado, “yes,” to the second of the questions above. After the fourth question, the district court sustained the defense’s objection.
It was not an abuse of discretion for the district court to overrule the defense’s objections based on Federal Rule of Evidence 403. Rule 403 allows the trial judge to exclude relevant evidence “if its probative value is substantially outweighed by the danger of unfair prejudice.” In this case, the evidence admitted was a single admission by Alvarado that he, after living in the United States for 25 years, had heard of seemingly innocent individuals who were caught driving drugs across the border. It is highly unlikely that this evidence resulted in unfair prejudice.
IV.
The government did not engage in misconduct by asking Alvarado whether the government agent witness was “mistaken” with respect to the translation of certain forms:
Q: So when Agent Ballard testified that he read it to you in Spanish, was he just mistaken?
[defense counsel]: Objection, your honor.
The Court: overruled.
A: Well, I don’t know, I don’t recall if he read it in Spanish.
This court has held that questions requiring defendants to offer opinions regarding the veracity of government witnesses are improper. United States v. Sanchez, 176 F.3d 1214, 1219-21 (9th Cir. 1999). It is likely that while government questioning requiring the defendant to respond whether a witness is a liar is improper, questions requiring an evaluation of whether the witness is mistaken are permissible. However, even if the questioning was error, it occurred only once, and with respect to a minor issue not central to the outcome of the case. The question of whether the notes of Alvarado’s interrogation were translated could not have been dispositive on the outcome of the trial.
While the panel rejects “balkanized, issue-by-issue harmless error review,” such analysis is necessary to determine where the district court has erred in the first place. Here, the court committed only one error — allowing in unqualified expert testimony — and committed no harm when it did so.
For the foregoing reasons, I must respectfully dissent.
