I think it's one component of an approach; it's one component to stop the drugs from coming in. But the last CSC deputy commissioner mentioned that it simply does not stop drugs. There's no prison in the world where drugs do not enter.
Given the significant amount of resources that have been spent in the last ten years, and the correctional investigator's finding that drug use has not gone down, you can't focus exclusively on drug interdiction. There needs to be a comprehensive approach.
