I would say the primary focus and priority is to keep the illicit substances from entering the institution, because of the consequences, obviously, of them making their way inside. It fuels violent acts within the institution, because of muscling that goes on within the institution, and debts that become owed. As well, obviously the usage of narcotics inside the institution is contrary to the plan for each of the inmates.
The primary focus is to keep those narcotics out of the institution. There are other ways, as my colleague has alluded to, where we know that inmates have contact in the communities and there are illegal enterprises, no doubt, being worked with the community. We've seen evidence of that in the past, but that doesn't correlate into what we're trying to accomplish in terms of ion scanning the individuals when they come into the institution. It's primarily to keep the actual substances out of the institutions.
