Last time I checked, in America, you don't get arrested for suspicious behavior alone - there has to be probable cause. Do people really get arrested simply because of suspicious behavior?
Thanks for the clarification...

Suspicious behavior (behavior generally considered outside established societal norms) is not a crime, so you can't be arrested for it. It may, however, be part of the articulable facts used to establish reasonable suspicion for the stop as well as the PC for the arrest.
But it's not a crime, in and of itself.
