If you have not been paying attention. He didn't say coons. They have done audio analysis and enhancing on the audio. The same that would be done in a trial. It wasn't coons he said.
There is no evidence at all that Trayvon was shot because he was black. The media tried to play the race card, and you idiots fell for it, hook, line and sinker.
Nobody is saying Zimmerman shouldn't go to prison. However he is clearly not racist.
In terms of stereotyping. YES, he could have done that. He may have seen what he thought was a black male, walking funny, with a hood over his face, and hands in his pockets and thought, hey, that guy looks suspicious. However it doesn't make him racist. It doesn't mean he shot the kid to death because of the color of his skin. Something the original articles were stating as almost fact.
