Leon Panetta, Director of the CIA, said "agency officers who worked in the program 'should not be investigated, let alone punished' because the Justice Department under President George W. Bush had declared their actions legal." Were there any officers who refused to work in the program? "Work"? I should say, Were there any officers who refused to torture?
The Nazis also declared that torture--among other horrendous things--was legal. After the war, they defended themselves by saying they were obeying the law.
