Even if only 5% of cops are dicks, that's way too many for people in a position of power. Ask the two in your family what they did the last time they saw a fellow officer pulling some kind of icky crap (this, racism against someone Indigenous, whatever). Maybe they're genuinely good people and called their fellow cops out, I don't know. If not, I'm sorry to say that they're part of the problem.

People involved in law enforcement have a higher obligation than the average citizen to follow the rules, except where specific affordances are made for them so that they can do their jobs. This is not one of those places.
