What are some aspects of the prosecutor's closing argument in a criminal case?

Fung and Black identify several aspects of the prosecutor's closing argument that they claim was error or misconduct. They claim two instances in which the prosecutor attacked the integrity of defense counsel (one of which Black claims was error under Griffin v. California (1965) 380 U.S. 609, 614), several instances in which the prosecutor improperly appealed to the jury's emotions, and one instance when the prosecutor improperly stated the law. We will assess each in turn.
