[JURIST] A California National Guard unit known as the Information Synchronization, Knowledge Management and Intelligence Fusion program [San Jose Mercury News report] is under investigation by military authorities to determine whether it was created to spy on civilians. Activists are concerned that the group's actions are similar to spying done on almost 100,000 civilians during the 60s and 70s. At issue is their monitoring of a Mother's Day anti-war protest at the state Capitol; a spokesman for the Guard said their duties involved only tracking media coverage [AP report]. The Guard has also erased a hard drive [San Jose Mercury News report] in connection with the program, frustrating outside investigators. The ACLU of California has objected to any military spying on civilians and has sent a protest letter to California Governor Arnold Schwarzenegger [PDF]. AP has more.
