I've actually read a book on the history of FBI files on writers and other celebrities and you would not believe how many people have FBI files with the most random information about them. As bad as TMZ, etc. today. Lots of it just rumors and even baseless commentary about the person and what the observer THINKS he or she believes or is up to, positions about the government and different issues. A lot of gossip combined with historical information. It's really pretty scary. It seems to me to be mostly "dirt" files on people, so I can only imagine what they might possibly have in a file on Michael if this is true. Anything could be in that file and it wouldn't surprise me in the least.
