I'd like to know everyone's perspective on this. Assuming that officers know the law, and that a citizen does NOT have to answer certain questions, why do cops get immediately angry and try intimidation tactics to get you to answer questions? Let's put out a scenario of a routine traffic stop.. Officer asks for identification. You comply. After that they begin a whole litany of questions that you don't legally have to answer. When you don't, even though they may have started out being nice and civil, they then turn into an angry, overbearing, authoritative asshat because... why?
