This is an older video, but it's still relevant more than ever today. I think we need more of this so people that don't know have better understanding about the split second decisions cops have to make. The biggest takeaway from the activist:
Of course, but I've kind of been obsessed with these videos since stumbling across this one. They're all over youtube. Most are at least 3 years old or older.
I saw a more recent one where the instructor was at a shooting range showing a group of community activist how fast an attacker can kill an officer and they weren't having any of it. The dude literally turned and shot a target in what seemed like less than a second, but the outspoken females in the group said that they'd have reacted quicker and stopped the threat without deadly force. It was laughable. I'll try to find and post it.
