The media seems to be implying that Z tried to make a "citizen's arrest" like Barney Fife. I can't see any evidence that Z confronted or even actually followed the other guy at all. The media keeps repeating the claim that he did wrong somehow by getting out of his car. But other than Observing and Reporting--which is what he was supposed to do--I can't see that he did anything wrong.
He probably made a simple mistake in judgement by giving the strange person he had just reported to the police the benefit of some common sense and therefore did not expect to actually be attacked. I would have stayed on the telephone. In TV interviews T's girlfriend has actually tried to justify the assault on Z by claiming that Trayvon thought he was defending himself against a Gay rapist, and ergo had to go beat him down. Hilarious if she were not so stupid. She undoubtedly did great harm to Trayvon's case and the jurors did not find her credible on the stand. Poor stupid thing. At least she told the truth (as she sees it).
As I said before, I have actually been confronted and challenged by Neighborhood Watch types many times, including some that really were @ssholes, thinking they were patrolling the DMZ. Whether they are armed or not, trying to go punch their lights out is not going to cut any ice with any cops who will still charge you with assault and battery--assuming that you are the one who bests the encounter.
Trayvon thought he could go beat down some guy because he was a stupid criminal in training. And that is what is really upsetting all the Trayvon supporters--that it so easy to connect the dots between a dead Black teenager and another future felon. Like a jaywalker who thinks he is smarter than the red light, Trayvon drew the short straw and got clobbered by a bus. It wasn't the bus driver's fault. The red light didn't discriminate against stupidity, let alone criminal stupidity.
The pandering that Obama and Holder are doing is quite amazing though. They must literally think that their electorate is a bunch of crackheads, and I am no supporter of Conservative Republicans by any means. This will be a field day for Rush Limbaugh types, and they are right. One self-described Liberal posting on a comments blog that they (Liberals) were just as outraged as all of the NRA type Crackas about what has happened, i.e., with the "Civil Rights" protests and the media and calls for blood, and are dismayed how race is being deliberately stirred up here. Well, one thing is for sure, if people like Obama and Holder are hitching their star to stuff like this, one can only wish them well--and with much more success with their own stupidity. Schadenfreude.
