Reports today that Saif-al Arab Gadaffi and three of Gadaffi's grandchildren have been killed in an allied airstrike. Which is a taste of tragedy for their relatives, and very stupid of the Alliance.
Nevertheless, the question of the Denialists is - will they apply the same rigorous standards of verification to these deaths which they insist on when thousands of innocent Libyans are slaughtered by Gadaffi's troops? If Gadaffi's word is good enough for them about his family, then the people's mass testimony should also be good enough for them.
Personally, I wouldn't be surprised if Gadaffi killed them himself. He is that desperate and deranged, after all. And in a very real way, he is the cause of their deaths.
