Who You going to believe? Your lying eyes viewing the signature of an FBI official on a document they claim does not exist, or the institutional word of the FBI? An Agency known for covering up their Forensic Lab Crimes, the JFK Hit, WACO, etc.
How about considering the possibility that High up folk in the FBI Lied to protect favored criminals who made the War on some Terrorists possible?
It's not early 1963 anymore. We have "Confessions of an Economic Hit Man" and "The Secret History of the American Empire" to guide us.
Too cheap to buy a book? Just download "War is a Racket" by General Smedley D. Butler to realize a handful of vile men have steered USA Inc. into doing crime for a century and most newspapers and media have been covering for their Crimes for a long, long time.
