You're completely out to lunch. This police officer was professional throughout, evn though Brunette was slurring one bald-faced lie after another. "She was driving". "I made the stop". "I had one beer". "I had only two".
All these lies and attempts to get away, from a guy who isn't just driving slightly impaired... he is visibly completely hammered. And you somehow come to the conclusion that the cop, who was being fed bullshit by a drunk who tried to play the celebrity card, is an asshole...
Do yourself a favor and stop trying to have an opinion about everything. Sometimes, like in this instance, it seems you come up with completely random stuff.
