In 1987, a judicial commission of inquiry headed by former [Israeli] Supreme Court Justice Moshe Landau had reported that “moderate physical pressure” [by the Israeli General Security Services G.S.S.] was defensible in cases in which an interrogator “committed an act that was immediately necessary” to save lives from grave harm. Israeli human rights organizations had monitored G.S.S. interrogations and concluded that some eighty-five percent of Palestinians interrogated had been tortured – subjected to methods almost identical to those currently being used in American military detention – and questioned whether such an enormous percentage of detainees were indeed “ticking bombs”. If those being tortured were all “ticking bombs”, why, asked an Israeli human rights organization shortly before the Supreme Court hearing, did interrogators take weekends off? “The lethal bomb ticks away during the week, ceases, miraculously, on the weekend, and begins to tick again when the interrogators return from their day of rest.” (source)
Whatever you think about the persuasiveness of the ticking bomb argument in favor of torture, or even it’s relevance to actual cases of torture, it’s difficult not see the risk of a slippery slope, especially given evidence like this.
