In 1993, Mr. Salem was an informant for the FBI who secretly tape recorded his interactions with the Bureau. These tapes reveal that the FBI possessed extensive foreknowledge of the Islamist plot against the World Trade Center....

Salems tapes seem to criminally implicate the FBI - either the 1993 bombing was a classic entrapment setup gone awry, or the FBI actively assisted the bombers even up to the moment of the explosion ( at the last minute, access to a key support column seems to have been blocked by FBI agents, forcing the bombers to place the explosive laden van close to a more secure column, which prevented a complete collapse of the structure).
