Doc Holliday is said to have cried after the shootout at the O.K. Corral.
A few find the experience morally liberating. They have broken the ultimate taboo, gotten away with it, and perhaps even been celebrated for the act of killing someone. And they like it.
Speculation is beginning to appear that George Zimmerman, the Florida man who shot and killed an unarmed teenaged boy, may belong to that second category. The conversation in Florida, including it seems at least one police chief, is that Zimmerman is a "ticking time bomb." It is unlikely that Trayvon Martin will be the last innocent person to die at the hands of George Zimmerman.
