How physical are you allowed to get during interrogations, with permission?
Very low levels. It could be two slaps in one interrogation, or to shake him, but not very strongly, or to put a cover on his head to scare him. We have never insulted a person's religion or humiliated them. There is no torture in the security services.
What do you make of the torture and abuse that took place in Abu Ghraib prison in Iraq?
I don't want to judge the Americans. In Gaza we have one security person for every 1000 people. In Iraq they have one for every 100,000. They have no information or intelligence on their detainees. Information is the beginning of interrogation, and if there is none, if there is no language between you and the detainee, sometimes you will use more power. That I presume is what happened in Abu Ghraib.
One for every 1000, versus one for every 100,000. Quite a difference.
