DO NOT!!!! be a dick to the cops. Yes there's an ocassional cop who's such a dickhead that that's the only thing they'll understand, but 99% of american police will not take kindly to some transient who thinks they're the shit. The thing to remember is that they DO have the upper hand in the situation. Some places have ridiculous laws on the books that a cop would never really enforce, unless he's dealing with some kid who's pissing him off. Believe it or not the cops really aren't out to get you, and some smelly kid with no money is not gonna be a glamerous bust. Half the time I find myself talking to cops its because some little old lady got scared by the look of me and called the cop shop. At this point, the cop is required to talk to me least I actually turn out to be a murderer or something, telling him/her to piss off and mind his own buisness is not gonna make his day (or mine) easier. Don't let em walk all over you, just calmly explain yourself and give him the info he asks for. If they're hell bent on arresting you, they just will, at which point being a dick is still not gonna help because 1. jail is cold and you will want a blanket when spending the night, 2. Bail officers are rarely at the station, and how quickly they get there and how much bail will be often has a direct relation to how the officers say you've been behaving, 3. If you give them reason to think you're hiding something they'll tear your pack apart often breaking and ripping shit (I've had the liner of my sleeping bag cut open) and lastly, some cops get a kick out of planting shit on punks and hippies (texas, lousiana, mississippi) and being a jerk gives them no reason not to, because to them, you're just another piece of shit society dropout who's only purpose on this earth is to make their arrest record look better.
