The point is that high ranking officers in the military are often sacrificed for decisions made at the top. It's done to placate the public after the end of the war.

Bush and Cheney did it when they claimed they knew nothing about torture going on by American forces. An American was prosecuted and sent to Leavenworth for 20 years because Bush and Cheney lied. Now he's out on parole on condition he never speak of what happened. He worked at Guantanamo.
