I have a joke for you: What happened to the schoolyard bully who was too stupid to pass a math class, so he threatened the smart kid with violence to do his homework, and then extorted him for money and then forced him to drink his bodily fluids, and then went home to do his favorite thing, which was to torture small furry animals? Give up? He grew up. And became a cop. I tell that joke to the con artists who call me on the phone claiming to represent policemen and ask for "donations".
This is so true, but it's also only the tip of the iceberg. They make decisions arbitrarily. I was run down by a woman who ran a red light to hit me as I crossed a crosswalk. She told the cop that some crazed jogger took a swan dive into her windshield. And what did he do? He came to me in intensive care as I was coming out of a coma from having my skull fractured, while I was strapped into a bed, my left arm nearly torn off, to write me a jaywalking citation. And then, because she said I was a crazed sprinting jogger, and he noticed I had an express mail package in my hands (with myself as the return address), and was 300 feet away from a post office, CLEARLY, Sherlock reasoned, the most likely explanation was that I was fleeing from the post office after stealing mail from them, that must have been why I was running, since the woman who hit me said I was running. So as I was semiconscious in intensive care, he also tried to get me to implicate myself for stealing mail in addition to telling me the woman's version of events as if it was what happened, and he visited the post office, and tried to get them to implicate me. He wrote me a ticket for 56 dollars and wrote up a police report that favored the driver, which her insurance company denied a claim based on, and went home to his 400 thousand dollar house, after another day in his 6 figure income career. Cops, you see, they don't care WHO gets the ticket. Just so long as SOMEONE else pays for their donuts.
