“Military prosecutors this year learned about a massive cache of CIA photographs of its former overseas ‘black sites’ while reviewing material collected for the Senate investigation of the agency’s interrogation program,” according to The Washington Post .  

“The existence of the approximately 14,000 photographs will probably cause yet another delay in the military commissions at Guantanamo Bay, Cuba, as attorneys for the defendants demand that all the images be turned over and the government wades through the material to decide what it thinks is relevant to the proceedings.”  

“It’s unclear whether the military prosecutors have been able to review all the photographs and why they hadn’t unearthed them years earlier…  The official added that many of the pictures appear to have been taken for budgetary reasons to document how money was being spent.”
