What a coward lol

edit: the more I think about this the more it seems like the absolute worst possible defense in this situation. By simply claiming he didn't pull the trigger he implicitly agrees that he was pointing the gun at someone. By saying "of course I'd never point it at someone and pull the trigger" he weakens any claim that he wasn't properly briefed in firearm safety, because he clearly understands that he should be treating even what he believes is a prop gun as if its a real gun and not point it at anything he wouldn't want to shoot. By claiming he didn't pull the trigger he's giving the prosecution a nice easy target to destroy with an expert witness that can say whether or not the gun was physically capable of malfunctioning in that way. And again on top of all of that it makes him look like a complete coward and liar that refuses to take responsibility for his role in the accident.
