Sure sounds like a bunch of twelve year olds talking here.
For all the stories of cops being bitches to you or your friends, there are millions of incidents every year in which nothing eventful happens. When a cop pulls you over, who the fuck knows, you could be recently released from a mental ward and have a pistol in the passenger seat ready to pull on the guy and shoot him. Cops deal with the fucking scum of society every day, I can understand that they have to be a little dickish and authoritative, because it helps keep themselves alive.
I'm not saying every cop is a pillar of justice, or not to question authority (know your rights, one of the most important classes I attended was about US law and the justice system), but given the state of things in this country, I dont think it should be unexpected. If we want friendlier policing, we need a lower crime rate and less violence. Once again, I'll bet for every bad cop story you have, a cop has a good one about nearly  being surprised and knifed by a crackhead.
