Phil Chinn's Ford Taurus moved along with the traffic on Highway 12, heading west in Grays Harbor County and beneath the Devonshire Overpass, where Washington State Patrol trooper Ben Blankenship was waiting. Blankenship put his cruiser in gear and moved down to the four-lane highway, pulling in behind Chinn's vehicle. Within a few miles, he hit his emergency lights. Chinn pulled over. It was May 6, 2007, early afternoon, the beginning of what the state patrol considers a routine traffic stop, but one that would cost taxpayers a half-million dollars.

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.
Most of his inside information, it turns out, was flowing the other way, according to interviews, court documents, and public records reviewed by Seattle Weekly. He was indeed a civilian employee at the fort—in its Army Force Protection intelligence unit. His true name was John Towery, and his mission was to spy on the protesters from within.

By settling, the agencies did not have to reveal details of the intelligence network that aided the stop. Those details could expose a broader spying operation, says Hildes. He is now trying anew to pry loose those sensitive police and military documents with another federal lawsuit, filed in January on behalf of other protesters. Hildes alleges the Army's infiltration of the Port resistance group and its military intelligence–sharing with local cops violates the federal Posse Comitatus Act, which bars the military from undertaking any unauthorized role in local law enforcement.
