You are characterizing police brutality - what we want to curb - as something they are trained to do… this is disingenuous at best. If a police officer kills someone innocent, or enters the wrong house and shoots someone… they absolutely should be held criminally accountable: as they have committed a crime.
Being a police officer shouldn’t excuse you from doing crime, come on.
Again: higher standards. And you should be asking yourself why you are okay with lower standards than “police should at least not be shooting innocent people in their sleep after entering the wrong house”
We really need better training for police: hopefully we at least agree on that…
