There's never a short legal response. I'm not here as a lawyer, but I think the standard is “substantial risk of torture”, and it has to be with respect to the individual, not generally.
I believe we did take all the measures that were reasonable at the time to ensure we were doing everything we could to minimize substantial risk. You can never eliminate risk altogether, and if that's what we're trying to do, then we will have a great deal of difficulty in being effective in peace operations. We have to have a process in place to try to prevent it from happening, and if we find it has happened, we have to do everything we can to stop it from happening again.
I believe that particular incident is the one that's referred to in the Federal Court in an affidavit by one of my colleagues. We took steps. We raised it at the highest level in the Afghanistan government, and they did what they should. They investigated and removed the person.
