The fact that a CIA operative has found his way onto the defense team
representing his former victims speaks volumes about the military
commission process. Taken in context, the presence of a CIA spy on the
defense team fits the show trial character of the proceedings as a
whole, which have been discredited time and again by interference with
the defendants’ right to counsel.
