Yeah that attitude many of them have is annoying... especially when they are off duty. But in fairness, when they're working, they never know when the shit will hit the fan, so when they approach any situation they have to seize control immediately. Being large & in charge, helps to keep anything from escalating. They have no way of knowing if you're a friend or foe, and a mistake could be fatal. I'm just thankful somebody is willing to do the job... and I try to avoid any contact.
