It's pretty obvious that they're not actually trying to make a defense. They obviously can't disprove a video of him pissing on a girl, so the only chance they have is something like OJ where the jury doesn't want to commit a black celebrity of an obvious and very wrong crime that he commit. If the jury does find him guilty, he'll just say that his lawyer was obviously incompetent and try to get a new trial. It's sort of smart and very sick.
