Gilbertson went to work for the group helping produce DVDs and encrypting email, according to an AP report. "I was alarmed and disgusted by what I heard, but I kept my views to myself and they were friendly," Gilbertson said. "They needed my skills, and I was perceived to be anti-government."
However, by October 2003 he said he became so alarmed by "what was going on around [him, that he] went to the police." He was instructed to mail police the material he had collected and the list of names, which he did, but he didn't hear back from police until he contacted them again after the July 7th attack on London.
Gilbertson, also reportedly a former Hells Angel, said he took the work to help makes ends meet for his family. "I'm good at what I do, and I've got kids to feed. And after a while, I became so alarmed by what was going on around me, I went to the police."
