>This attitude is less hard to understand when you’re not looking at it through the filter of cases where that happened not to be true

Nope, the attitude of "I never make mistakes" still baffles my mind. I get that most people they're dealing with are causing some amount of trouble, they should still regularly doubt their instincts. That would also go a long way to answering demands to "stop being racist."

>It’s a system where day in and day out, almost everyone you encounter is a really shitty human being.

If they hold that mindset, they should just extend it to themselves and the other people in the criminal justice system.
