Oliver Kirby always believed that the attack was deliberate so what's new here? Other than the fact that 40+ years later, at the age of 82 he suddenly remembered that he had seen some transcripts but of course he could not produce these transcripts. Yawn.
Are you talking about mass killings like "the black september" when Jordan threw your palestinian asses out of the country? The number of casualties in what resembled a civil war is estimated at tens of thousands, and both sides [Jordanians & Palestinians] were involved in intentional killing of civilians. It was a turning point for Jordanian identity, as the kingdom embarked on the program of "Jordanization" of the society.
