ive never needed the cops, they have never helped me directly, the one time i tried to be a good citizen and call the cops on a bad situation they took almost 30 minutes, acted like a couple of complete douche bags, and made the situation worse. but i have had plenty of experience with cops, yes i have encountered the occasional good cop, some were actually really great people, who were able to use common sense in handling the situation rather than being the typical dumb shit cop looking at the law like its completely black and white.
but for the most part its bad experiences, abusing their power, trying to scare me, trying to get away with more than they are supposed to, and in almost every case, power tripping like crazy.
most cops just suck ass, the law they enforce, and how they enforce it is completely retarded. when you fuck with peoples freedom as much as they do, it should be a life threatening job.
