Spoken with the purest of ignorance. You see Professor, I wouldn't even begin to try and tell you how to speak or interpret spanish. I would come across just as ignorant as you are currently trying to argue gun handling.
It takes ALOT of training to handle a gun IN A STRESSFUL SITUATION. Sure anyone can pull a trigger, and if that's all someone thinks is required in handing a firearm safely, has absolutely no business being around one, much less handling one. So, as an assassin, Wilson probably is pretty incompotent. But given that he was neither targeting Brown for terminaition, so as to get in the closeset, best proximity to cap him with 1 shot, when Brown either wasn't looking, or perhaps restrained in some way, nor was he expected to even use his firearm, until Brown became an imminent threat, his compotence as an officer was perfectly within rationality
