Well isn't that interesting?
This seems to be something easy to verify, as to be honest, when a 'document expert' starts making claims identifying specific creation software (Adobe Illustrator or Photoshop), my BS indicator pegs. So I downloaded the copy of the long form off of the Doug Vogt website, a copy off of the White House website (yep, you can still save the document, no problem..), a turner website, the azstar website, and finally, the copy I downloaded off the first links that appeared on FreeRepublic when the story broke.
I opened each file using notepad++, a very common text editing program, and discovered something interesting. Four of the copies are formatted exactly the same, one is not. The Doug Vogt copy has a dramatically different formatting in the start and end of the file. All five files share the exact same creation timestamp string (though the Doug Vogt one somehow leaves off the time zone portion of the string following the Z), the Doug Vogt file includes a separate modified string.
So one copy is dramatically different in formatting, and includes a separate modified string. I have to speculate, as I'm being kinda lazy here and not actually testing, that Doug used the 'save as' feature on whatever PDF viewer he had and this created the modified timestamp. And in doing so, it created different formatting for the PDF file as well. The only significant change between the five files appears to be the formatting and the modified timestamp.
Anyone interested is welcome to give it a go themselves, as I said, all of this is easily available online to try out. Wordpad should work just as easily as notepad++. Did Doug Vogt find a special smoking gun version of the document? Or did he inadvertently contaminate the document he was going to examine? Or did some ubersecret conspiracy go out and make sure that all the other documents including the one on my personal computer exactly matched so I'd question Doug Vogt's methods of handling the archival of the very document he planned on examining?
