911 Guilt: The Proof is in Your Hands - Jim Hoffman

Presentation by mechanical engineer Jim Hoffman.

In 26 minutes, Jim systematically dismantles the excuses given by the government for collapse of three World Trade Center buildings and clearly proves that these buildings fell due to controlled demolition.

Jim's site at http://www.911research.wtc7.net/index.html is the best site for in depth research into the subject. Some of the info on this site cannot be found anywhere else anymore. Most of the slides in the video can be found here.
