Serena Soto stands trial for mail fraud. During closing argument the prosecutor tells the jury that Soto's decision not to take the stand shows she has something to hide. The trial judge gives no curative instruction. The comment violates the Fifth Amendment because the prosecution may not invite the jury to treat the defendant's silence as proof of guilt.
Sabrina Shah is charged with assault. After receiving Miranda warnings she remains silent during police questioning. At trial the prosecutor offers her silence to rebut an insanity defense. The evidence is inadmissible because post-Miranda silence carries an implicit assurance that it will carry no penalty.
Stephen Shaw faces embezzlement charges. The court instructs the jury that it may consider Shaw's decision not to testify as evidence of guilt. Defense counsel does not object. The instruction constitutes plain error because the Fifth Amendment forbids any suggestion that silence supplies proof of the charged offense.
Sean Steele is convicted after a jury trial. At sentencing the prosecutor argues that Steele's refusal to allocute demonstrates lack of remorse and warrants a longer sentence. The court may not draw an adverse inference from the silence because the Fifth Amendment privilege continues to protect the defendant after conviction.
Simon Stern elects to represent himself at trial. When the prosecutor comments on Stern's failure to testify, the court must intervene. The right of self-representation does not diminish the Fifth Amendment protection against adverse comment on a defendant's silence.
Selena Singh enters plea negotiations and agrees that her statements may be used to impeach her at trial. Later she remains silent at trial. The government may not use her trial silence itself as evidence of guilt. The waiver applies only to the earlier statements, not to the constitutional bar on commenting on silence.
No. The Fifth Amendment prohibits the prosecution from commenting on a defendant's failure to testify or inviting the jury to treat that silence as substantive evidence of guilt.
