If you think like a coward you will live the life of the coward.
As for myself and many others we draw a line in the sand and make our stand.
Zimmerman acted very foolish. He should not have got out of the car, and should have done what the dispatcher told him to.
He didn't. He acted very foolishly. That doesn't mean that his life was not in danger, but does mean he put himself in a stupid situation. He had called in that there was a strange man walking around acting suspicious, and had started following the man. He was advised not to get out of the car, and not make contact. He did so.
Was that wise? Would any lawyer or cop say “Good move!”? His life was turned upside, and the best he can hope for is that the civil rights charges that are coming are thrown out. He can't go home, and has a bounty on his head, for what? Being foolish is often a very costly thing.
