How have courts dealt with the issue of prosecutorial misconduct on appeal?

Respondent argues that appellant has forfeited this issue on appeal due to his failure to object or, in the alternative, that appellant's claim is without merit. We find, even assuming counsel's objections to some of the alleged misconduct or error were sufficient to preserve the issue and/or that it would have been futile to object further, that any error or prosecutorial misconduct was harmless under any standard of error. (See Chapman v. California (1967) 386 U.S. 18, 24; People v. Watson (1956) 46 Cal.2d 818, 836.)
