I get the impression that a lot of school bullies get into law enforcement. they don't have the skills/credentials to do anything else and they have the streak of cruelty that you need to fit in.
I knew a guy in my early 20's, not white, who wanted to be a cop. Once he told me "If I have a bad day, everyone gonna have a bad day." I dont talk to him anymore because he became a cop and turned into a fucking asshole.
"The bishop's smile, a gilded, hollow thing, hides taxman's greed, and whispers of the king; the knight's sworn oath, a rusted, broken chain, while village elders plot for whispered, selfish gain; no judge's word, nor lord's decree rings true, in thirteen twelve, what's left for us to do?"
