Where is the instinct in these guys? I know you have to be prepared for anything and part of that preparation I want to believe is not shoot first and ask questions later. MOST people are by and large law abiding citizens, and law abiding citizens often get nervous when being stopped by the police because they're simply not used to being in those situations and are nervous because they're not the kind of people who even want to look like they're intentionally doing something wrong.
Not one damn thing about these last two incidents were even remotely close to a situation that should have resulted in anyone being harmed. It's just cops that were IMO looking for trouble.
