George Zimmerman has proven that he's a dangerous individual time and time again since being found innocent of murdering Trayvon Martin. For instance, he was recently arrested for assaulting and threatening his girlfriend. He's known to carry weapons and has other charges against him from the past. Zimmerman is dangerous.
A man who shot a young man under questionable circumstances and continues to act erratic and violent is indeed very dangerous. It is not a matter of opinion, it is simply an objective fact that someone who kills and threatens to hurt other people is very violent. How can anyone deny this?
