some guy named BB posted it thinking it would exonerate the cop
http://en.wikipedia.org/wiki/Tennessee_v._Garner
so I read it and judge ruled against the shooter which is a critical distinction to say the least!
I still think that case has merit here. While it deals with fleeing suspects, it backs up that the police have a right to shoot if they perceive a threat. It doesn't matter if he is outside the car, 15 feet away, etc... A lot of whiners seem to go on, and on about the distance, etc.... It means nothing.
It's a basic tenet of self defense in both civil and police guidelines. If the officer can clearly articulate that he felt the man was a threat then he has the right to shoot. He can shoot them unarmed, he can shoot them running, etc... All he has to do is convince one juror.
