The MJ-12 Documents are one of the most controversial aspects of ufology to date. Many call them outright hoaxes and others say they are the real deal. Mr Stanton Friedman has done much research on them and has turned up many thousands of documents that help the cause of ufology.
My theory of the MJ-12 documents is that they are well made fakes with some errors in them for skeptics to find. They were created just in case any real documents ever get through the security and released to the public. That way, everyone would call the real deal a hoax. This is an ingenious plan when one starts to think about it.
