The 9/11 Truth movement is a carnival of characters, earnest, loony
or both. Jarrett Murphy uses this to advantage in his colorful
article "The ABC's of 9/11." (The movement also has many intelligent,
hardworking members but they're less entertaining to read about.)
However, separate from the peddlers of theories about nukes, pods and other
special effects are important questions about the war games being conducted
on 9/11; the highly anomalous put options on United and American Airlines; the
role of Dave Frasca of the Radical Fundamentalist Unit of the FBI and Promis
software which provided the foundation for Total Information Awareness.
These issues are dealt with in Mike Ruppert's Crossing the Rubicon, (which Murphy
mentions) the second best selling book on 9/11 after the Commission Report. The
equally complex engineering questions on the collapse of the towers are
explored by Jim Hoffman of

These two, along with
