I can't speak for anyone else, but I'm not interested in hanging anybody, being against the death penalty and all.
However, not being privy to the information the police have, I have to wonder why it is that he is not -- at a minimum -- in a holding cell. Have they already determined it's self defense? Has he already been booked and charged and arraigned and released on bond? Did I miss all of that?
Otherwise, why the heck isn't he in jail right now, pending all of this? He shot someone to death. There is no dispute about that. I am not familiar with how the system works to that degree, but I am very surprised he's not at least in custody. Or is he, and I missed that, too?
Those are not snarky questions, and I don't expect anyone else to answer them (though it'd be nice *wink*). I'll google. But that's my beef with the goings on at the moment.
ETA: I see, not enough evidence to arrest him. Really? So, if you shoot someone, and everyone and their dog know it, you admit it, etc., since you claim self-defense, they can't arrest you? Really? I feel incredibly stupid here, but I don't understand that.
