Zimmerman acted recklessly and irresponsibly. Florida permitted him to own and carry a gun. But it did not give him a license to be a vigilante, or law enforcement training and the judgment that goes with it. Had he abided by the HOA's rule not to be armed while on patrol, and stayed in his car as the police dispatcher advised, Martin would be alive, Zimmerman would not have been charged, and America would have been spared more racial strife.
