WHY did the guy dive back into the vehicle?
(I'm "hard of hearing" - so couldn't make out the audio)
Depending, I MAY have opened fire, too - as it almost seemed on the video - the guy may have been going for a weapon.
When "Stuff" happens that fast - reaction and training take over.
He was reaching for his wallet which is what the trooper asked for, then when the trooper told him to get out of the vehicle he did just that and trooper opened fire.
Like you I think it was a good shoot and think police should have a free hand to shoot anyone entering or exiting a vehicle at anytime.
When the SC legal system plays softball with him and he is exonerated, you, me, and the nation's police will get our wishes on that.
