Professor William Beeman at the University of Minnesota passed along a note today from "a colleague with a U.S. security clearance" about the mysterious Syrian site targeted in a Sept. 6 Israeli airstrike.

The note raises more questions about the evidence shown last week by U.S. intelligence officials to lawmakers in the House and Senate.

The author of the note pinpoints irregularities about the photographs. Beeman's source alleges that the CIA "enhanced" some of the images. For example he cites this image:

The lower part of the building, the annex, and the windows pointing south appear much sharper than the rest of the photo, suggesting that they were digitally improved.

The author points to more questions about the photographs of the Syrian site.
