“Well, you could answer the officer’s questions, or you could stand on principle, refuse to comply and be taken in, then questioned.”
Yeah those pesky principals, almost like rights and stuff.
There's not that fine a line between cooperating with law enforcement and unreasonable search and seizure. Being asked to identify yourself is not out of line, and is compelled legally in most states. The "where are you going" thing verges upon onerous, but is understandable coming from an officer attempting to determine whether our FReeper don-o was cruising around the neighborhood, looking to break into cars, since he fit a description that was provided by a concerned citizen, who had observed someone who looked very similar, peering into parked cars.
