Because you have never had any formal training on the laws governing use of force

Cops’ “formal training” includes courses on “kill-ology”. They get rewarded with paid vacation and the adoration of people like you. I’ve run into people like you on reddit. As long as I keep responding, you’re planning to fire off one of these pro-murderpig comments every 24 hours or so to see how long you can keep me going.

As with reddit, I can choose to not participate. I’m making that choice. Inflict yourself on someone else. I’m free to leave.
