Why couldn't George Zimmerman just pull out the gun and say get off of me or I will freaking shoot you? I have never seen him say that he didn't mean to kill Trayvon or show any sort of remorse. It makes the whole thing worse. He doesn't seem upset or shaken up that he killed someone ever. In the photos that night, in the interview tapes, in his reinaction video. He is so cold blooded it makes self defense hard for me to buy.
