It can be a tough question, but there are processes, mechanisms, and expertise that can be drawn on to make those assessments. It obviously involves careful analysis of law enforcement and security practices in the country from which the information is being received, both in a general sense and in a specific context. There is no perfect equation or process through which information can be filtered and a clear and conclusive determination made that it has or has not been the result of torture. That's why there's a threshold here. What we're looking for is whether there is a serious reason to believe it has been attained through torture.
