I think cops are like airplanes. Every day there are thousands of flights to points far and near but the only planes that you hear about is the ones that crash or catch fire or sit on the taxi way for 3 hours. Cops are the same way.
Every day there are thousands of cops that go to work. Fill out tons of paperwork. Deal with sassy speeders/lawbreakers. Risk their lives day in and day out for pay that is not stellar to say the least.
But the only cops that you hear about are the ones that go over the top and abuse a citizen to such an extent that it gets on the news.
Those rogue cops are no friend to the good (vast majority) of cops. They give all cops a bad name and in so doing, increase the risk the good cops face from a jaded public.
