Man oh man it's almost like I refuse to acknowledge someone's opinion especially when they admit to having an inclination that inhibits impartial judgment stemming from prejudice.
It's not impartial judgement if the entire system for policing is built upon immunity: which it is. There are only extremely rare cases where police are held accountable, and usually only after massive backlash.
Also there are biases in literally all opinions. No one is a perfectly logical human being. But whatever you have to say to make yourself feel superior.
