That's the problem with guns. I believe in the right to self-protection, but this clown Zimmerman actually thinks he was not only protecting himself from somebody who hadn't threatened him, but he thought he was being a savior of his neighbors. And, yes, I'm sure he was a major nutcase all his life until killing Trayvon, and I also doubt he will keep away from arms.
OJ, in my opinion, is guilty as sin. Of course, I didn't see him do it. That's how he got off. Nobody saw it. But I do think the evidence is conclusive. And although he waited many years for his true stripes to make the headlines again, I believe he has had other incidents that nobody knows about before the Great Kidnapping Caper. in my opinion these two are psychopaths (ditto for Casey Anthony). A psychopath doesn't change who he is. He can get smarter about playing the "I am normal" game and some can maintain longer than others can. I believe Ted Bundy fooled the famous Ann Rule who writes true crime books. She met him and worked beside him and did not guess he was a psychopath.
