Why yes, Assad is still a vile evil tyrant. And he may be the only viable counterweight to IS. What to do…

The State Department has obtained 27,000 photographs showing the emaciated, bruised and burned bodies of Syrian torture victims — gruesome images that a top official told Yahoo News constitute “smoking gun” evidence that can be used to bring war-crimes charges against the regime of Syrian President Bashar Assad.

The photos are “horrific — some of them put you in visceral pain,” said Stephen J. Rapp, the U.S. ambassador-at-large for war crimes, in an interview. “This is some of the strongest evidence we’ve seen in the area of proof of the commission of mass atrocities.”

The photos — a small number of which will be put on public display for the first time on Wednesday at the U.S. Holocaust Museum — were smuggled out of Syria by an official regime photographer who has since defected and is known only by his code name, Caesar.

They were shown at a closed-door session of the House Foreign Affairs Committee in July where Caesar, wearing a hood, testified. They are now being analyzed at Rapp’s request by the FBI in part as an effort to determine whether any U.S. citizens may have been among the victims — a finding that could be the basis to bring criminal charges in the U.S. against officials of the Assad regime.
