Explanation for DanT
The "stuff" is not "Top Secret". It is a technique of MASINT of the National Directorate of Intelligence akin to what was called "vacuum cleaning". Think of Public Key Cryptography as a hint. Only a few have the "key" to decode the hidden messages. As DES and others have mentioned it is clear that Sarfatti is magnet for all sorts of people. Most are harmless but some are not. Sarfatti has already supplied invaluable Counter Intelligence in the War on Terror and continues to do so. His work has been described as at "the core of MASINT" by a top USG Intelligence Officer.
