A quibble: A killing that occurs in the course of a fistfight is by definition not "cold-blooded."
Working just from the facts that aren't seriously disputed, it's evident why the police didn't automatically arrest a veteran Neighborhood Watch captain who had already called for police back-up, and who had obviously been jumped and beaten. Especially when the dead guy the cops found was the real one—a gold-toothed, tattooed, 6-footer with hair on his upper lip and probably skinned knuckles—rather than the PhotoShopped 12-year-old whose picture has been promoted.
More facts are always nice. But as far as Zimmerman's actions go, only a political opportunist would conclude that the case is any more complicated than that Trayvon picked the wrong guy to punch.
What would be productive to explore is whether the recent rash of burglaries in the gated compound was actually the work of Trayvon. He had a contact there—his father's girlfriend—and he had been suspended from school three times, including for truancy. And he was caught at school, not just with a marajuana baggie, but with a screwdriver and women's jewelry. That suggests either a burglar or a poofter. I guess time will tell.
Police departments don’t generally let a murderer walk free if they have evidence of the crime. While we don’t have all the facts here, we definitely have plenty of evidence of media bias. It’s so blatant. They don’t even hide the fact that they aren’t really interested in the truth. That’s not sensational enough. Back when I went through school, reporters were only supposed to report facts. Opinion went on the editorial page. Our media, like many modern institutions, is a complete joke. Unfortunately, I won’t be laughing when blood is shed over this crap!
