Arye Roter, the top legal adviser of the Shin Bet, talks about how the organization gets along without torture. It didn't always, of course, and for a while in the 1970s and 1980s it had precious little to be proud of in that respect, but the organization that stands at the center of Israel's ability to thwart something like 95-99% of the Palestinian attempts to murder Jews manages to do so without torture, except in the extreme and rare cases of "ticking bombs". The Americans and British could learn a bit from them.
Read this one carefully, as it's a rare event when you get this close a view of what goes on in the Shin Bet (which is really called the Shabak).
PS - Those awesome success figures don't relate to shooting out of Gaza.
