[on the participants in his documentary 'The Gatekeepers, about Shin Bet, the Israel security agency] The thing for me is to try to understand if they had another interest in speaking. Especially on those really morally questionable issues that we dealt with: the targeted assassinations, the torture, the right to give the order to kill without a trial. On those issues I can say, first of all, they have to defend the decisions that they took, but I didn't feel that they tried to whitewash what they did.
