That's a ridiculous statement. It's the dictionary definition of prejudice. You don't know "most cops" or how they handle the public. It's not even likely that most cops are anything different from most people. Some are bad, most aren't. Some are lazy, most aren't. Some are fat, tall, black, white, asian, gay, criminals, dumb, geniuses, whatever. They are a cross section of society.
And suggesting that armed citizens defend victims of police brutality is a good way to get people shot. Engage brain before posting.
Gay cops? Never heard of such a thing? Are their batons soft?
