You have a point there Evie, however I think others, including witnesses, can give locations of mass graves. Individual killings by his subordinates may not be known specifically by Saddam. WMD's, well if our or British expert thumb twisters cannot get info from his subordinates, what makes me thinks he could say anything of value just to save his *** from the death sentence. Besides, now recent news is that a Pakistan (sp) individual or group may have put Iran, Iraq, and N. Korea on to the "bomb".
Your point would also have weight with me personally if this guy was a leader of a country that didn't have terrorist or extreme religious violent radicals willing to blow themselves and innocents up. I don't believe Hitler had these types and we & the world would have executed Hitler (after a trial of course). I had indicated that with outside "soldier of fortune" experts being paid enough, no prison in Iraq could hold Saddam. Also, think of the terrorist/suicide people who would start hijacking and holding important hostages wanting an exchange. We would naturally loose some important people as we don't negotiate under that premise.
