...those guys that you see in BT, wearing clean white shirts with the tails out, shined boots, creased pants, fresh haircut...they are cops too, and they are armed. And again, they are not there to hassle you, unless you make a big scene, get physical or very verbally abusive with someone, piss on the street, or do something egregiously negative. They will let you get away with things that would get a local's ass kicked, and are there to protect you from street predators and your drunk self. So go and have fun, fuck something, but use normal and reasonable caution, and maybe you will cheat the hangman one more day.
