Without a doubt, members of the U.S. armed forces committed vile, criminal acts upon prisoners in their custody. It appears that the concept of "softening the prisoners" was a widely accepted principle, and if it turns out Rumsfeld knew about it he must go. Bush is Commander in Chief and must deal with the concept that the leader is responsible for those he or she leads. While I do not personally hold Rumsfeld or Bush directly responsible(at least at this time), the fact that these attrocities occured under their watch and that it seems impossible or at least improbable that the administration just found out about this, I have yet another reason to want this Administration out of office.
