Had I read through this article years ago I'd feel very different about this then I do now. My default position is, and always will be, to suspect the government is at fault but that being said I still understand why police officers do what they do.
I'd like to leave something that has helped me to understand the thought process of most police officers. There is a youtube channel called "Think Like A Cop - The Rest Of The Story" run by an..... interesting character. He's an expolice officer who, by all accounts I've been able to find, was very good at what he did.
He presents the "other side of the story", the side of the police that you don't usually hear well developed. From watching many of his videos, I can pretty safely assume that he doesn't trust the government, I'm fairly sure he isn't racist, and I'm fairly sure he isn't sexist. What is more representative of him is that he tries his hardest not to be politically correct. It is my opinion that even if you don't respect him as a person, you can probably respect his methods of thinking about problems and his experience as a police officer. I'd hope some of the people here watch some of his stories about how cops react to situations as he makes things that seem 100% unreasonable seem much more sensible.
For instance his motto is "no people belong on the ground" which refer to to people who want to be adversarial to the police. This policy is blanketed across all people that cops deal with and after watching some of his police shooting videos you can see why. When he shows videos of cops getting shot or killed he mostly shows videos where the police don't follow this golden rule. This rings true with all of the cop shooting videos I've seen.
I'm not saying he is right, I'm not saying I'm right, I'm just saying he offers a very "interesting" perspective that I think many will enjoy.
