Absolutely.
One example, which I detailed in my written remarks but didn't mention earlier, is the case of a man whose brother was interviewed by the Afghanistan Justice Project. After the brother was tortured in the custody of the NDS, after he had been rendered unconscious, his thumbprint was placed on a document that included a confession. In Afghanistan, thumbprints are often used in lieu of signatures. He was then revived medically and beaten until he was rendered unconscious again.
I think that presents a very good example of the incentive behind the torture of many of the detainees in the custody of the NDS. If they don't know how to prosecute a case without a confession, the motivation, particularly with the eyes of the international community on the Afghanistan justice system to actually prosecute cases, is present for them to use coercive means and torture.
