Newly declassified documents reveal that an active member of Students for a Democratic Society and Port Militarization Resistance in Washington state was actually an informant for the US military. The man everyone knew as “John Jacob” was in fact John Towery, a member of the Force Protection Service at Fort Lewis. The military’s role in the spying raises questions about possibly illegal activity. The Posse Comitatus law bars the use of the armed forces for law enforcement inside the United States. The Fort Lewis military base denied our request for an interview. But in a statement to Democracy Now!, the base’s Public Affairs office publicly acknowledged for the first time that Towery is a military operative. “This could be one of the key revelations of this era,” said Eileen Clancy, who has closely tracked government spying on activist organizations.
