Hmmm...Bush is not the only one within our government that has actual knowledge and proof of those events. If one of those with inside knowledge happens also to be opposed to Bush's foreign policy, especially the GWOT, or else someone who still carries around a grudge for the GRU (old Soviet military intelligence), then the facts will leak. I can think of at least two elements within the CIA that fit that description.
Where else would Getz be getting his intel if not from intel? (Rhetorical question.)
