It comes with being an officer I think, a prime example is what just happened in Oakland... walk up to a car on a normal traffic stop and get executed just for being a cop or because that person doesn't value human life or has issues and doesn't want to goto prison. When you become an officer, in these hostile times, you really have to separate yourself from civilians because of how easily your life could be taken away just for doing your job. So, if I'm an officer and I get a bad vibe from you... damn right I'll do my hardest to make you feel like an ant compared to me, just so you don't get the slightest idea to do something stupid. I've never had a cop make me feel powerless, even after 8+ tickets they're still as courteous as could be with me.
