On Tuesday night's 'AC360,' one of George Zimmerman's lawyers, Mark O'Mara, said that co-counsel Don West had not consulted him before using a knock-knock joke during his opening statements. That widely-criticized tactic 'should've been rethought,' conceded O'Mara, who also said they will make a 'dynamic decision' as the trial progresses on whether Zimmerman will take the witness stand.
