Here's one that probably should walk free, Cory Maye. Nobody seems to be taking up his case. Cops broke into his place on a warrant for another place.
---Let's summarize: Cops mistakenly break down the door of a sleeping man, late at night, as part of drug raid. Turns out, the man wasn't named in the warrant, and wasn't a suspect. The man, frigthened for himself and his 18-month old daughter, fires at an intruder who jumps into his bedroom after the door's been kicked in. Turns out that the man, who is black, has killed the white son of the town's police chief. He's later convicted and sentenced to death by a white jury. The man has no criminal record, and police rather tellingly changed their story about drugs (rather, traces of drugs) in his possession at the time of the raid.---

Life is a crap shoot. You lay your money down and take your chances. If you have led a good life, and have good friends, you might be allowed to win. If you are a loser, you get to lose.
