Presumably, you don't know George Bush well enough to know, either, and yet I get the feeling you don't think he is a good person. Regardless, if Pelosi did know about the waterboarding and even pressed the CIA to do more to extract intelligence from detainees, would that make her a bad person (or, at least, not a good person) who should be tried as a war criminal?
Let me ask you about the goodness of Obama. Forget about raping a child to save lives. Let's go one step further. Do good people excuse extrajudicial executions with missiles containing cluster bomblets and dismiss the anticipated killings of women and children who happen to be in the vicinity at the time a High Value Target is sighted? Can a good person justify the killing of women and children if he thinks it will save American lives? If it can be shown that Obama ordered the firing of at least one BGM-109D Tomahawk cruise missile into the Yemeni village of al-Ma'jalah on December 17, 2009, resulting in the deaths of fifty-five people, including 14 women and 21 children, is he still a good person? Amnesty International questioned the legality of the attack. If it was, in fact , illegal, would Obama then also be bad person who should be tried as a war criminal?
