So, if a cop orders you to suck his cock you should just go along with it? Or maybe we should expect police officers to meet some kind of standard. If we let cops act like Judge Dredd then that is what we will get.
That's the strawiest straw man ever in history and you know it. Yes, ideally cops would all be paragons of perfect virtue, but that is NOT REALITY and never has been and never will be so you have to do the pragmatic thing to stay safe
