Barrett Brown was just released from prison last November after four years behind bars for, among other things, posting a series of videos in which he appears to threaten an FBI agent. How things escalated to that point in the first place is a complicated matter involving email hacks, drug addiction, and the murky world of private intelligence contractors.

Often straddling a line between journalist and participant, Brown's rise to prominence tracks that of the hacker collective Anonymous, perhaps best remembered for its campaigns against Scientology. Media outlets characterized Brown, not always entirely to his liking, as the spokesman for Anonymous, and it would be his association with hackers that would later put Brown on the FBI's radar.

For his part, Brown believes that it was his investigation into several private intelligence contractors following the hack of a firm called HB Gary. Brown and his team discovered in the emails that several of the firms had joined together into a conglomerate called Team Themis, and that one of Team Themis' projects was to develop potential lines of attack against critical organizations like Wikileaks and journalists such as Glenn Greenwald.

Brown sat down with Reason TV in the Dallas headquarters of D Magazine, where he now works covering city council meetings, to talk about life in federal prison, the state of the private intelligence industry, what an ever-leakier world means for the future of U.S. politics and culture, and his plans to create a decentralized activism network based on lessons learned from Anonymous meant to shake up media and governmental institutions.
