Can prosecutors comment on a defendant's failure to share his story with police? State v. Fairbourn Explained

In State v. Fairbourn, the Utah Court of Appeals addressed multiple claims of prosecutorial misconduct in a high-stakes attempted murder case, providing important guidance on preservation requirements and the scope of permissible cross-examination.

Background and Facts

Defendant lunged at a police officer with a seven-inch knife after threatening that the officer was “about to fucking die.” The officer shot Defendant three times in response. At trial, Defendant testified that his actions were meant as surrender, not attack. During cross-examination, the prosecutor questioned why Defendant had not shared this explanation with a detective at the hospital after the incident. The prosecutor also asked Defendant to explain discrepancies between his testimony and eyewitness accounts, and elicited testimony from the officer about his thoughts during the encounter, including fears about his family.

Key Legal Issues

The court addressed three prosecutorial misconduct claims: (1) improper comments on Defendant’s post-Miranda silence; (2) improper questioning about witness discrepancies; and (3) prejudicial questioning about the officer’s mindset. The court also considered whether testimony about the twenty-one-foot rule was properly admitted.

Court’s Analysis and Holding

The court applied plain error review to the unpreserved misconduct claims, emphasizing that appellate courts review trial court decisions, not prosecutor conduct directly. The court found no plain error regarding the silence comments because the prosecutor asked why Defendant didn’t share “this story” rather than why he remained silent, focusing on credibility impeachment rather than Fifth Amendment violations. The questioning about witness discrepancies was proper because it sought clarification rather than asking Defendant to comment on other witnesses’ veracity. While the officer’s testimony about his family was improper, it was harmless given strong evidence of guilt and jury instructions against bias.

Practice Implications

This decision highlights the critical importance of specific preservation at trial. When Defendant’s counsel objected to the prosecutor’s closing argument as “burden shifting” rather than a Fifth Amendment violation, the court found any error was invited. Practitioners must articulate the precise legal basis for objections to preserve appellate challenges. The decision also clarifies that credibility impeachment through prior inconsistent silence may be permissible when the defendant testified and spoke to police about other matters.
