Here’s a video that shows some of the many members of the military, FBI and CIA who objected to the use of torture in interrogations. Some of them resigned their commissions, others were punished for their objections. But they did the right thing regardless of the consequences. They included Col. Morris Davis, the lead prosecutor at the military tribunals at Guantanamo Bay; Lt. Col. David Frakt of the Air Force JAG corps; Lt. Col. Darrel Vandeveld, also a Gitmo prosecutor; Alberto Mora, former general counsel for the U.S. Navy; and FBI interrogator Ali Soufan.
And here’s a longer one specifically about Col. Davis, who resigned his commission rather than use evidence obtained under torture at the military tribunals at Gitmo.
