When Green MP Keith Locke requested his Security Intelligence Service (SIS) file in early 2009 he found that the service had been keeping tabs on him since he was 11 years old. Locke came from a family of activists and had been involved in protests from his youth. His father, Jack Locke, was a long-time member of the Communist Party. His mother, Elsie Locke, had left the Communist Party in 1956, but was an activist for peace and justice causes throughout her life. Locke's SIS file contained more than 400 pages on him, much of it covering mundane activities. Locke was particularly concerned by the fact that the SIS continued to monitor him even after he became an MP. The SIS themselves became more open to releasing information to the public after Warren Tucker's appointment as director in 2006.
