They're just pictures!

I'm pretty sure it was a rock hard commitment, given by then candidate Obama, to release all information, including pictures, of any detainee abuse. Now, I'm a Republican, so I don't like playing gotcha politics, but this is ridiculous. I agree 100% with President Obama's decision, but why is this a reversal? Why would he ever have made this commitment? Is it possible he flat out lied to his supporters, and they bought it hook, line, and sinker. Or did he truly believe that he could follow through?
