Cheney Fear Torture Investigation

I am too disgusted by Cheney's loathsomeness to even comment on this.

There is no doubt in my mind that an investigation is warranted here. In fact, so far as I can tell, a much broader investigation than Holder has in mind is probably morally obligatory. Since when did we decide that we are not even permitted to investigate possible wrong-doing in this country? Since when were the answers to all such questions simply supposed to be intuited...or assumed?

Cheney seems desperate to keep the facts from coming to light. Wonder what could explain that?
