Rodrigo Pino-Noriega appeals his conviction for importation of marijuana and possession of marijuana with intent to distribute. 21 U.S.C. §§ 841(a)(1), 952, and 960. He claims that he was denied his right to testify in his own defense, that the district court improperly admitted lay opinion testimony as to whether his post-arrest statements “made sense,” and that the district court improperly allowed the prosecution to present testimony regarding his post-arrest silence. We have jurisdiction pursuant to 28 U.S.C. § 1291, and we affirm.
FACTS
On October 13, 1997, at approximately 5:00 p.m., a United States Border Patrol pilot was flying surveillance over Imperial County, California, when he observed a brown pickup truck illegally cross the border from Mexico about 10 miles west of Calexico. The pilot observed the truck travel north, away from the border, until it met up with a grey sedan. The two vehicles traveled in tandem through El Centro and Brawley, California, until they reached a farm equipment yard about 40 miles from the border.
As Border Patrol agents on the ground closed in on the yard, the pilot observed a man in a light blue t-shirt and dark pants exit the driver’s side of the truck and enter the passenger side of the grey sedan. The pilot informed the other agents that the driver of the truck, wearing a light blue shirt, had entered the passenger side of the sedan, and that the truck was still in the yard. While several agents pursued the sedan, the truck was secured and found to contain over a ton of marijuana.
With Border Patrol agents in pursuit, the sedan slowed, and a man in a light blue shirt and dark pants jumped out, ran over to the canal next to the road, and jumped in. A few seconds later, a pursuing agent pulled up to the spot where the blue-shirted man had jumped into the canal, saw that the man had floated about 25 yards down the canal, and ordered him out of the canal and arrested' him. The man *1093 arrested, Rodrigo Pino-Noriega (“Pino”), is the appellant herein.
As the pilot watched from above, the sedan approached Brawley, with another agent in pursuit. When the scout car sped up and began driving erratically in an attempt to evade pursuit, the agent, following Border Patrol policy, broke off the pursuit. The pilot watched the car enter Brawley and stop at an apartment complex. Two people exited the car-one wearing a red shirt and dark pants, and the other wearing a dark shirt and dark pants. These two suspects were never located.
That evening, Pino was taken to the Calexico Border Patrol station. He was wearing a light blue t-shirt and dark blue pants. Pino was informed of his Miranda rights, in Spanish, and agreed to waive them. He was interrogated by DEA Special Agent Andrew Pappas, and Emilio Cotero, a Deputy Sheriff in Imperial County and a member of the DEA’s Narcotics Task Force. Pino denied any involvement with the marijuana smugglers, although he did admit to having illegally entered the country. Initially, Pino stated that after he crossed the border, he jumped in the back of a brown pickup truck driven by a friend. After riding for a while, he thought that the truck was going to collide with another car, so he jumped out and landed on the canal bank, where he was arrested by the Border Patrol.
However, after being questioned by the agents for further details, Pino changed his story. He said that his friend never showed up, and that he hitched a ride for two to three miles and walked the rest of the way. Since he admitted to crossing the border sometime between 3:00 p.m. and 5:00 p.m. that afternoon, and since he was arrested around 6:00 p.m. some 40 miles from the border on a 100-plus degree afternoon in the desert, the agents found the new story suspect. After additional questioning, Pino changed his story again. This time, he said that after his friend failed to show up, he hitched a ride on a white pickup pulling some sort of trailer by jumping onto the rear bumper of the truck without the driver’s knowledge. Supposedly, he rode this way for about 40 minutes, then jumped off when he thought the truck was going to collide with another car. Again, he landed in the canal.
Since the agents found this story no more credible than the others, Deputy Cotero told Pino that his story did not make sense, and told him that he would tell him what had really happened. The deputy told Pino to stop him if he got it wrong, and proceeded to relate what he had learned from the Border Patrol about the events observed by the pilot from the plane. Pino initially said nothing in response to this recitation. When told by Deputy Cotero that he would be taken to the Imperial County jail and booked, Pino, stated “that while he was in the military, he learned the — capable [sic] of what traffickers can do and that we cannot arrest anybody in Mexico and that money in Mexico could buy anything, so what’s the use?” At that point, the interview ended.
Pino was subsequently indicted and charged with the importation of marijuana and possession of marijuana with intent to distribute, in violation of 21 U.S.C. §§ 952, 960, and 841(a)(1). A jury trial was held at which Deputy Cotero testified as to the several inconsistent statements Pino made after his arrest. In so testifying, Deputy Cotero commented that Pino’s stories did not make sense. In relating Pino’s statements, he mentioned that, after being told what the Border Patrol pilot had observed, Pino “stood there quiet.” Pino did not take the stand during the trial.
On January 15, 1998, the jury informed the judge that they had reached a verdict, after approximately two hours of deliberations. Pino, the attorneys, and the judge gathered in the courtroom to receive the verdict. Before the jury was brought in, however, Pino’s counsel told the court that: “Mr. Pino wants to address the jury. Apparently, he’s unsatisfied with the way the trial was conducted by me.” After an extensive colloquy with Pino, the court determined that he wanted to testify in his *1094 own defense. He wanted to tell the jury “how [he] got to that place.” Pino told the court initially that he had always wanted to testify, but that his attorney and several other people had argued against it, and he had felt “pressured throughout.” Pino did tell the judge that he had, at some point, “agreed not to testify.” He indicated that he agreed not to testify under the impression that his attorney would bring out the points he wanted brought out, but that he did not think that his attorney had ever done so. When Judge Keep asked Pino why he had not said anything before, he said: “I tried to say something, but I was taken away.” The judge pointed out that this was not true, and that, after the close of evidence and the arguments, the jury had been sent out of the courtroom, and the court had conferred with Pino regarding whether he wanted to be present should the jury have any questions. The judge asked why Pino had not told her then that he wanted to testify. He responded: “I understood it to mean that you were going to be here asking me questions. When you said whether I wanted to be here during the questions, I understood it to mean that I was going to be asked the questions.” Pino also stated: “I don’t want to pay for something I have not done.”
The judge decided not to let Pino address the jury, since they had already reached a verdict, stating: “It’s too late. We’ll get the verdict of the jury. We’ll see what the verdict is. And after I excuse the jury, then we’ll set another hearing date.” The jury was then brought in, and returned a guilty verdict on both counts. Immediately after the jury was excused, the judge directed that new counsel be appointed for Pino, and set a status conference to discuss a hearing on the issue. An evidentiary hearing was held, and Pino’s new counsel argued that Pino should be granted a new trial. The judge held that Pino had validly waived his right to testify in his own defense, and denied the motion for a new trial. Eventually, Pino was sentenced to 97 months in prison.
DISCUSSION
A. PINO WAIVED HIS SIXTH AMENDMENT RIGHT TO TESTIFY IN HIS OWN DEFENSE
Pino argues that he was denied his Sixth Amendment right to testify in his own defense when the district court refused to reopen the evidence and allow him to testify after the jury had reached a verdict, but before that verdict was announced. We review a district court’s decision not to reopen the evidence for abuse of discretion.
United States v. Huber,
The right of an accused to testify in his own defense is well established, and is a “constitutional right of fundamental dimension.”
United States v. Joelson,
However, while waiver of the right to testify must be knowing and voluntary, it need not be explicit.
See id.
A defendant is “presumed to assent to his attorney’s tactical decision not to have him testify.”
Id.
The district court has no duty to affirmatively inform defendants of their right to testify, or to inquire whether they wish to exercise that right.
United States v. Edwards,
The question presented by this case is
token
a defendant who wishes to testify must speak up to assert that right. Clearly, if the defendant says nothing until after the verdict has been read, the right has been waived.
Edwards,
The Supreme Court has made clear that, while the right to testify in one’s own defense is fundamental, that right “may, in appropriate cases, bow to accommodate other legitimate interests in the criminal trial process,”
Rock,
This Court has previously held that a defendant’s right to testify is not unduly restricted by rules limiting a defendant’s testimony to
relevant
matters,
Moreno,
In
Martinez
we explained that “it is important that the decision to testify must be made at the time of trial and that the failure to testify not be raised as an afterthought after conviction.”
Martinez,
Thus, once there is a verdict, it is too late simply to “reopen the evidence,” and a new trial becomes necessary. Allowing a defendant to have two trials, one based on his lawyer’s strategy (where the defendant does not testify) and one based on his own strategy (where the defendant does testify), does not promote fairness, justice, or order,
see Martinez,
The fact that in the instant case the defendant informed the court that he wanted to testify moments before the verdict was read, rather than moments after, does not make any difference. A new trial would have been necessary just the same. The jury had completed deliberations and reached a verdict. The same “bell” had already been rung, and could not be un-rung any more easily just because the verdict had not yet been spoken aloud. Even the attorney appointed to represent Pino at the post-trial hearing regarding Pino’s untimely request to testify appeared to concede that a new trial would have been necessary in this case if Pino’s request had been granted. Clearly, then, there is nothing to distinguish this case from those cases in which the defendant has been held to waive his right to testify by waiting to speak up until after the jury had delivered its verdict.
See, e.g., Nohara,
*1097 B. THE DISTRICT COURT DID NOT PLAINLY ERR IN PERMITTING A GOVERNMENT WITNESS TO TESTIFY THAT PINO’S POST-ARREST STATEMENT “DID NOT MAKE SENSE”
A district court’s evidentiary rulings during trial are reviewed for an abuse of discretion.
United States v. Figueroa-Lopez,
Pino challenges several statements made by Deputy Cotero in his direct testimony, in which Cotero expressed the opinion that Pino’s various post-arrest statements “did not make sense.” At trial, the defense failed to object to several of these statements, but did object to some of the now-challenged testimony on the grounds that it was speculative. At no time during trial did the defendant ever make the argument that any of Cotero’s testimony was improper lay opinion testimony. Nonetheless, on appeal, his sole argument against the admissibility of this testimony is that it was improper lay opinion testimony, admitted in violation of Federal Rule of Evidence 701.
Clearly, where the testimony was not objected to at all before the district court, we review for plain error.
United States v. Simas,
Federal Rule of Evidence 701 “permits a lay witness to give opinion testimony as long as the opinion is ‘(a) rationally based on the perception of the witness and (b) helpful to a clear understanding of the witness’ testimony or the determination of a fact in issue.’ ”
United States v. Yazzie,
C. PINO’S RIGHT TO REMAIN SILENT WAS NOT VIOLATED
Pino claims that allowing Deputy Cotero to testify to the fact that Pino remained momentarily silent after the deputy recited the events observed by the
*1098
Border Patrol pilot infringed on Pino’s Fifth Amendment right to remain silent. We review de novo whether references to a defendant’s silence violate his Fifth Amendment right to remain silent.
United States v. Ross,
The Fifth Amendment guarantees that “[n]o person ... shall be compelled in any criminal case to be a witness against himself-” U.S. Const, amend. V. This privilege is protected by informing criminal suspects that they have “the right to remain silent,” pursuant to
Miranda v. Arizona,
However, the rights guaranteed by
Miranda,
including silence, can clearly be waived. Thus a defendant who voluntarily waives his right to remain silent after being informed of his rights cannot prevent the introduction at trial of statements he makes after he waives that right.
Anderson v. Charles,
Therefore, since Pino had validly waived his right to remain silent, comment on his silence would only have been impermissible if he had reinvoked his rights, either totally or selectively.
See United States v. Garcia-Cruz,
We note, finally, that the above analysis assumes that the prosecution actually did “comment” on the defendant’s silence. In fact, both Deputy Cotero, in his testimony, and the prosecuting attorney, in her summation, simply mentioned the fact that Pino “stood there silent” for a moment before going on to state: “that while he was in the military, he learned the-capable [sic] of what traffickers can do and that we cannot arrest anybody in Mexico and that money in Mexico could buy anything, so what’s the use?” It is evident that the prosecution was more concerned with introducing this statement than the silence which preceded it. The silence was mentioned more in passing, in setting the stage for what Pino said next, than as a focus in itself. Likewise, the prosecution never indicated in any way that this silence somehow provided an inference of Pino’s guilt. It was simply mentioned, not stressed, and no one ever attempted to draw any meaning from the silence at all.
See United States v. Ochoa-Sanchez,
*1099
Thus even if mention of Pino’s silence was error, it was clearly harmless. To determine whether improper comment or testimony regarding a defendant’s silence is harmless, three factors are considered: “(1) the extent of the comments made; (2) whether an inference of guilt from silence was stressed to the jury, and (8) the extent of other evidence suggesting the defendant’s guilt.”
United States v. Baker,
AFFIRMED.
