Eye for an eye... He shoots his victim once, gun jams, leaves, comes back and shoots her again, has a friend bury her while she's still alive. Pretty humane of him.
I just watched the little channel 4 news bunny's account of the execution. Sounds like a horrible, horrible way to meet your death.
It couldn't have happened to a more deserving person.
All things happen for a reason. Maybe a greater being decided he hadn't suffered enough, and that a painless death was too good for this animal. I have no more sympathy for him than I would the writhing body of a rattlesnake that had it's head chopped off.
edit - I forgot. I'm not happy that it happened, if it would have gone off without a hitch, he would have been joined 2 hours later by the other one. That's the tragedy here. This is going to, quite possibly, be an end to capital punishment in OK. For that reason, this is a horrible thing.
