@Emilski - Tell me if I am wrong but could that not be considered profiling and to be totally honest illegal tactics in order to just arrest someone?
I know someone that although they did drink underage at college, they only had a couple beers, but because it was a college town they were randomly stopped while walking down the sidewalk. The police demanded he take a breathalyzer because they were testing people at random.
This guy, not knowing that he could refuse or demand to know why he was being asked to, did it, blew a .03, and was sent to jail and charged not just with underage drinking, but also public drunkenness and disturbing the peace.
After consulting a lawyer it was determined that what the police did was illegal and the charges were dropped because they followed procedure wrong and could not just randomly stop people like that walking down a street.
I am just wondering how police in other college towns get away with doing this as at least in this one case it was considered illegal to profile in such a way and harass citizens like this and say they were disturbing the peace because they had a minute amount of alcohol in their system.
