This video cinches it for me. He had a gun and he posed a threat.
1. The length of the standoff is reasonably long. Clearly Scott was not following any instructions.
2. There are just too many cops around for this to be "blue protecting blue." That many cops are not going to cover up a shooting if no gun was present. That many cops are not going to plant a weapon without someone saying, "Hey, wtf?"
3. Why did the wife keep yelling, "Keith - you'd better not! You'd better not! Come out of the car!" Clearly she feared her husband was about to do something stupid. She knew he was a threat - you can hear it in her voice.
So, I would say a justified shooting. Take a good look where the body ends up, too. When he moved, he must have moved aggressively and fast.
All that being said, I wonder if cops should carry a hold-harmless so they could quickly get consent from a person like this wife and say, "Hey - you want to go talk some sense into him? If you do, we can't be responsible if you get hurt. Sign here." I would want that opportunity with my spouse or kids, even at the risk of personal harm to myself.
