He wrote Crossing the Rubicon - a book about 9-11 in which is accurately identifies Dick Cheney as the chief orchestrator of 9-11.
He went around the USA and gave presentations to crowds in which he exposed a lot of things about 9-11 that they did not know.
As I watched more of the videos about this man's life, I was amazed that I, too, did not know about him earlier. He was very articulate and extremely knowledgeable.
They say he killed himself in 2011. Many times, in the Post 9-11 era, people that had spoken out about 9-11 just happened to commit "suicide." Whether he did or whether he was murdered, we will probably never know.
Here are some www.youtube.com videos featuring Ruppert.
I encourage people to learn about this man. He was exceptional in his ability to analyze 9-11 (and other issues) and communicate his views to others. We are lucky to have had him get involved in the 9-11 crime investigation.
