This is a direct result of the militarization of the police. A 30 year retired LEO explained it to me this way: Police are being traing in law enforcement rather than police work. In Police Work, you see someone with their feet up on a bench, you tell them to put their feet down. In Law enforcement, you walk up, write them a citation. End results to the community, person puts his feet down. In Police Work, the situation has just ended, in Law Enforcement, it has just begun, now there is a trial, court costs, lost productivity, bad feelings towards police, fines, jail time, etc, etc.
Now, the police are being trained to take control of the situation by immediately dominating and controlling the "suspect" and environment. This is very escalating behavior (and the reason many people think that LEOs are A-holes). I am seeing more and more of this on youtube. Police pulling guns on people who are clearly non-violent. I saw a video of a LEO shooting an unarmed man on a motorcycle for no visible reason.
I was not there for this shooting, nor have I seen the video. BUT I will guarantee the police approached the victim in a very agressive manner, with guns drawn, yelling at him the entire time. How would it have turned out had one of them drawn his weapon and stayed out of the victim's line of sight, while the other approached calmly and said "excuse me, please keep your hands in sight. Are you carrying a gun?" Police covered, no escalation of violence, everyone goes home that evening. Yes, this will not always be an option, and won't always work. But I have been on the receiving end of both of these approaches, I know which one my adrenalin hit and I was motivated more by fight or flight than reason.
You can have peace. Or you can have freedom. Don't ever count on having both at once.
