Here's a guy who has a little extra in the guts department. Gavin Seim, who describes himself as a constitutional activist, recently filmed himself flagging over a police officer who was driving an unmarked car in Grant County, Wash. The cop seems partly amused, partly in disbelief as Seim asks him for identification. "This is my ID right here," the officer says, pointing to the police patch on his uniform. "That's not ID, sir," Seim counters.
