Context is key. Those of you posting about "more experience with LEO than you" come from one perspective, and those presenting the dark side of LEO's come from another.......Personally, if only my perspective were considered, LEOs fall into only one category: almost useless. Can't catch the jackoff that did a hit & run on your car while leaving their front bumper as evidence, can't catch the robbers that broke into your mother's house and left fingerprints everywhere, can't find anything better to do than pull you over for no reason on a lazy Sunday and then lie to your face (and to the four others in your car) only to give you a warning, and etc.......Based solely on my own experience, I know to avoid certain small fiefdoms (call counties by the locals, but really run by the medieval lords calling themselves county judges) in some areas of Oklahoma due to the absurd corruption in the ranks of the local cops. Based on other anecdotes, I know to avoid whole areas of the country where the cops pose a significant threat to your person and/or property--like all of Delaware near I-95/I-295, and all westbound Interstates through Tennessee, and some others.
I have had experience with cops across the country with me being on the 'wrong' side through a few traffic stops, I will be the first to admit I have a lead foot. But in all but one or two of those cases the police have been professional and courteous, I had no problems interacting with them and even the one exception I can think of off the top of my head the cop defaulted on the side of caution and I can't fault him too much for that.
With attitudes like most cops are "almost useless", "useless as tits on a bull", "pose a significant threat" or are absurdly corrupt I am not so sure it is the cops you and some others here apparently encounter are the only ones to blame for your bad encounters with law enforcement.
