So, if I amputate the wrong leg, all I have to do to avoid an appearance before the Healing Arts Board or a Judge is retire (Petraeus) or claim a "scheduling conflict" (Clinton)? What difference should it make to a House investigation whether or not Petraeus is the CIA Director on the day of the hearing? He was Director on the day under investigation. And since when is it acceptable for a cabinet secretary to snub his/her nose at a House committee? This is an ongoing criminal conspiracy.
