That's when Chinn noticed, on the trooper's dashboard, a computer printout with a picture of Chinn's car—actually, his parents' vehicle, a Ford Explorer. He'd been driving it the day before. Today he was driving his Taurus. Chinn suddenly realized this was hardly a routine stop: They'd been looking for him, in either car.

Unbeknownst to Chinn and others at the time, Port protesters had a double agent in their ranks. He went by the name John Jacobs and identified himself to fellow demonstrators as a civilian employee at Fort Lewis. When he joined the movement in early 2007, he offered to provide the inside scoop on Fort operations, and over the next two years would prove a trusted, loyal anarchist. He was given access to the activists' confidential communications, and told his new friends he wanted to start his own faction of war resisters.
