Is it improper for a prosecutor to imply that a defense counsel has fabricated evidence?

"In People v. Herring (1993) 20 Cal.App.4th 1066, the prosecutor implied defense counsel had suborned perjury by instructing the defendant to invent a consent defense to a rape charge. 'The prosecutor's comments, i.e., "[m]y people are victims. His people are rapists, murderers, robbers, child molesters. He has to tell them what to say. He has to help them plan a defense. He does not want you to hear the truth," were clearly improper and misconduct. His argument inferred that all those accused of crimes whom defense counsel represented are necessarily guilty of heinous crimes. Additionally, he impliedly denigrated the presumption of innocence and the requirement that guilt be proved beyond a reasonable doubt. More egregious, he inferred that defense counsel suborned perjury. It is improper for the prosecutor to imply that defense counsel has fabricated evidence or to otherwise malign defense counsel's character. [Citations.]' . . . .
