Don't forget about Klaus Barbie, the "butcher of Lyon" France's number one wanted war criminal. These weren't just scientists they were sadist torturers and concentration camp directors. Barbie was found in Boliva by French Nazi hunters. His court case is on video record. One of the few times the CIA "appologized." I wonder if he tortured Che himself?...the chambers have been uncovered there and the mass graves I believe.
