I'm not a computer guy so I have no idea about this kind of stuff. But CNS seems to think that Bush's documents recently uncovered by 60 minutes may be fakes.

Another memo and another and another
edit: i would like to point out that i have no opinion yet as to whether or not they are faked. i'm no expert in typesetting. i thought some of you would have fun picking it apart though. if they are fakes, it is pretty ballsy though.
