Arizona just passed an extreme immigration law that requires police to ask people for their immigration status papers if they look like they might be illegal immigrants. (What does an illegal immigrant look like? :confused:)
That is obviously a very silly law, but it only reflects what the police is doing in reality anyway. At least here. Example 1: I was never stopped by police on a highway without having done anything wrong, except once when I was in a car with a Hungarian license plate. The police thought we´re bulglars on the way home. Example 2: before there was the Schengen zone, I could never cross a border without getting searched. Long hair, old car => dope smoker.
