I watched it several times and didn't see him dragged at any point. It appears that he fired before he fell over.
I think all the evidence, including the lies, are in agreement on that point.
But notice the other argument being offered in this thread, 60 arrests, uncooperative, etc. - again, not saying this is a winner, but if the cop had argued that instead of something like "shot so he'd stop dragging me," it would be easier for the DA to take a pass on the case.
OK, he wasn't dragged. He was just hanging on (for dear life) to the car door for 3 seconds and a distance of 20 feet. Normal people call that being dragged. What do you call it?
It appears that he fired before he fell over.
Well DUH! Good thing that he did fire before he fell over. Otherwise he wouldn't have hit his target.
