Personally I'm a fan of creative spelling. And, if guns cause crime, then keyboards cause spelling mistakes so I think you should lighten up, okay? ;)
Seriously, the more I read this, the more I think that (a) If this gets in front of a grand jury, things may change; and (b) maybe the dead guy was universally acknowledged (or at least the police might have thought so) to have "needed killin'", since everything else about this shoot is, at best, questionable.
Somebody comes up to me out of the blue and says,"I think you just attempted rape and I don't want you to go anywhere and I'm drawing my weapon to see that you don't," I'd charge the sucker with assault. I must be missing something here.
You can go through life relying in your spell checker if you want. Care to learn something? Look in a dictionary. "Defence" or Defense" -your choice genius.
