Not really. Just check this site, a conservative forum, for links to gross cases of police abuse. The video doesn’t lie and the cops aren’t judge, jury and executioners. The Prosecutor’s office and Courts work intimately with law enforcement on the local level.
Although I like to believe most cops are honest and decent, too many have morphed from peace officers into a unionized version of carabiniri or VOPOS. Believe, as a guy old enough to be your granddaddy, this is no longer your granddaddy’s police force.
