Went back and played in in slow motion. This screen capture is imperfect, but seems to have been when the "shoot" decision was made. Taken totally by itself, and not as part of the scenario (crawling while terrified, with his legs crossed)...maybe.
He also had encountered the purse, and might be off balance. I've never tried crawling with my legs crossed. But again, a half second later, it was obvious the guy was empty handed.
Unless you are spring-loaded to shoot, wait the extra half-second. I did 40 years ago and it meant I didn't shoot anyone - as a non-cop. But non-cops are held to a HIGHER STANDARD than cops are. And I had a T-shirt on that day, not body armor. And I was alone and outnumbered. But I hesitated.
I get the feeling that a lot of 'force on force' training is geared to teach "Don't hesitate!" But not hesitating killed a totally innocent guy. I find it unacceptable that while I would face consequences as a CCW civilian, cops do not.
Take into account the total scenario. What does it take to draw a gun? I've practiced in front of a mirror, so maybe that is why I was confident the guy was NOT going for a gun. It isn't like the movies. To draw a gun, you need to get hold of the gun. Take into account the guy's behavior while crawling.
Heck, if nothing else, get and use body armor for situations like that. What I saw in the video was a rush to fire. In combat, we expect people to go in "harm's way". Cops need to as well. At a minimum, they should be held to at least as high a standard as a non-cop would be held.
