When you see a US General under a cloud making the rounds on the talk shows you can bet they are covering their ass.
I don't see how they can do anything other than Court Martial her. From the Taguba report, it is abundantly clear that the FRAGO giving MI control over Abu Ghraib was given 19 November 2003, but Karpinski and her command rebuffed the transfer of command, openly disrespected the TACOM of the 205th, and continued to operate the facility as if they were still in charge. I've never seen such open contempt for command leadership and refusal to carry out orders as I've seen with Karpinski. Her brigade was tasked to provide I&R, but she made no attempt to communicate this mission to her command, and she did not set up any procedures to ensure the mission was carried out. This is more than incompetence: it is sabotage, passive and intentional, of the mission.
