Yes there are police procedural issues and training problems in lots of places in the US which cause lots of problems. Rev tends to post some of those and the issues he shows on video and have in the past, I've been appalled seeing. One where a older gentleman with Dealer tags
gets pulled over by a cop and gets tazed - however in that case, the cop was 100% in the wrong. The premise for pulling the guy over was for an outdated inspection sticker (a Non moving vehicle violation - not a misdemeanor) where the cop then pulls the attitude and illegally slams the guy on the hood and ground tazes him and then arrests him. The funny thing here is, the cop didn't know a car with dealer tags doesn't need a valid inspection sticker (this happened in TX).
The result of that incident (sorry for taking this off topic but I'll try to bring it back around) was the Cop was fired after an IA review
and may face charges himself.
The purpose of me bring that up was I don't jump to conclusions often as I treat each and every incident separately. Not all cops are bad, not all cops are badly trained and we tend to hear about the bad one's. In the case of Johnson, I don't see bad cops.
In the case of Vasquez, I saw a person who had no business being a cop and the public is safer with him seeking employment elsewhere.
