“one of Pamela Geller’s readers did some heavy-lifting with Photoshop and discovered what appears to be an embossed seal on the back of Obama’s certificate.”
You can’t emboss one side if a piece of paper!
And we only have an image of the front. The point is that digital image analysis finds that the image contains evidence that the scanned document had an embossed seal, which was mirror imaged on the front. Meaning the clerk who embossed it had the clamp backwards and didn’t press as hard as the clerk who embossed the Decosta certificate that’s been circulated for comparison.
