Who Is Anonymous?

I cannot say for certain if the real Anonymous posted this video. One question that has never been answered satisfactory, is "who is the hacker group called Anonymous?" Rumor has it that Anonymous consists of rogue elements of the military/industrial complex. That might explain why they are so damn good at what they do and might explain why they focus their attention where they do. Then again, would someone of that skill and talent quote and publicize Jesse Ventura? Maybe not.
