Senate foreign relations committee chairman John Kerry said on Friday that he was concerned the release of photos depicting the abusive treatment of detainees in U.S. custody could become "propaganda tool" for terrorist organizations. In an interview with the Huffington Post, the Massachusetts Democrat was asked to respond to news that the Department of Defense would be releasing 44 photos pertaining to the harsh handling of detainees at prisons in Iraq and Afghanistan. "I think showing the truth is always important," said Kerry.
