For the best commentary, see the Elder of Ziyon. It’s the Elder who points out the central issue that the others miss:
“However, the sheer nerve that he shows here takes the cake. He finally decided to step down after Israel was ready to show evidence that he was paid by one of the sides that he was supposedly investigating. Instead of apologizing for hiding this very salient fact about his history when he was appointed to the commission, Schabas instead lashes out at those who exposed his utter contempt for the concept of impartiality.”
Good riddance to bad rubbish.
