The sad part is that he probably was being honest. I've worked with city/county/state/federal law enforcement, never as a leo, and I've heard some wild shit. I get into a state unit and they'll go over a list of shit I can't do. I get into a county unit and they ask me what kind of firepower I brought.
There's a lot of unrealistic bleeding heart bullshit when it comes to use of force, like the Michael Brown thing, but there are a lot of cops out there that do whatever they want. They get away with it because of human nature. Who watches the watchmen? I was once at an energetic materials workshop where the 50 people in the room had to introduce themselves, all law enforcement. One guy said he was in internal affairs; you should have heard the groans. The rest of the time there I heard people shit talking him, asking why he would admit that, etc. It's against human nature for them to attack their own tribe. It's against their self interest for them to hold their coworkers to the same standard. That's why cops always talk about doing right 99.99999% of the time and holding each other accountable, and then you see a video of a cop clearly going over the line and the ten other cops on scene don't do shit to stop him. It's also against human nature to deny yourself the means to do what you need to do. I was riding with one cop when the topic of unmarked traffic enforcement came up. When I said I was against it, he asked why in a disgusted tone. I told him it was dangerous to pretend you weren't the police, and then suddenly demand that people believe you're the police. You wear a uniform for a reason; not another peep. Local government is also unwilling to prosecute the people that feed them cases, or piss off the tribe, or disrupt their revenue stream. And courts have also given police a wide latitude to do their jobs, way too wide in my opinion.
I've got mixed feelings about the direction we're headed. The us vs them gap is getting wider, police are catching hell for non-issues, but I'm seeing a turnaround in police attitudes. Ten years ago it was across the board "I'll put two in your chest if you don't raise your hands fast enough cause I'm going home tonight" and now I see a lot more cops siding with citizens. I also saw a recent state police class and it was like 80% Ron Pauls, and that's the kind of person I'd rather have in uniform.
