Utah State Univ Prof Posts Forged Docs in Effort to Prove CBS Memos Authentic for Kevin Aylward's article on this.
The Utah State prof was trying to prove that the CBS memos were typed on a typewriter.
He created docs with Photoshop cut and paste to prove his point.
Here are two comments from the Wizbang site's discussion of the docs the USU prof created:
----------------------------------------------
The 2nd superscripted 'th' has been added later. It doesn't have the edge pixelation the letters on either side have. It looks "clearer" than the set of letters it was supposedly typed along with.
This is caused by forgery; admittedly a better forgery than the original see-BS forgery (which was totally outrageous) but a poor forgery still.
----------------------------------------------
Simple explanation: the cut and pasted the TH into the image of the document to make it look like the TH he created on his typewriter matches the TH from the CBS memo. If you look at the PDF and the PSD files, you can see that the 72 in the date "1972" a few lines above the superscript TH also appears to be pasted in.
Considering the professor's credentials, this lameness does not surprise me - he's a technical writer. We are not known for our mental acuity. At least, I'm not!
Excellent catch on this!
