An upstate appellate panel criticized a prosecutor’s “pervasive misconduct” during closing arguments as it overturned a burglary conviction on other grounds.

“The prosecutor inappropriately and repeatedly vouched for the credibility of prosecution witnesses, suggested that the defendant was a liar, characterized the defendant’s testimony as ‘smoke and mirrors’, and otherwise improperly denigrated the defense,” the Appellate Division, Fourth Department, said in People v. Walker, 515/14.
