The problem is we've created a siege mentality in Police culture, and that siege mentality causes a reciprocal siege mentality amongst the police. It does not encourage quality applicants to police forces and the antagonistic nature of the job drives the siege mentality ever farther until we end up in this vicious cycle where cops profile black men to death and black men avoid and/or antagonize cops on every possible level.
'member when the TSA first got started? It was full of every veteran grandfather with a desire to help his country. Then it got shittier and shittier and shittier until the employees at the TSA now are the thugs that lack the competence to do a real job but glory in the opportunity to inflict their will on people who can afford to travel.
I know a cop who legitimately protected her town from a crazed coworker who was involuntarily committed because he threatened to mow down the elementary school. She was fired, sued under whistleblower protection and won over a million dollars. And her facebook feed is full of cold dead fingers rhetoric because she honestly believes that people should have the right to shoot anyone who threatens them in the face at any time.
None of this is going to get better until we can get out of the bunker.
