Have to agree with Derid on this one.

Getting the story from the paper / news is one thing. What really happened is likely another.

One or more individuals in the car may have said something they shouldn't have ( Ergo, I'm going to kill you ), may have reached for the glove box, under the seat, etc, etc.

I have my doubts the guy was sitting quietly in his vehicle reading his bible after being asked to turn his music down. :D

Is also a reason you keep your hands on the steering wheel during a traffic stop, so the officer doesn't mistake your actions for a hostile one and shoots you for it :D

I'll wait to form an opinion until after we get the details on what transpired during the event.
