Just to reiterate, 99% of all of our visits coming into the institution are approved and allowed, and that may or may not involve the use of the ion scan. In terms of conducting a threat risk assessment, there's a series of checks and balances in the document that need to be followed through. Again, as Mr. Coons has said, we use the ion scan as a possible detection tool, as well as the drug dog, X-ray machine, or metal detector. Also, for those coming in for family visits, we physically go through their suitcases to check to see if there's anything in there that would represent contraband.
In addition to that, we also review the information contained in our visitor review board, for prior visits of the offender by the particular visitor who is coming in for a day visit, whether there were any hits on the ion scan or any hits by the detector dog or metal detector.
As well, we review the case management file to ensure that the offender is in compliance with his or her correctional plan and is adhering to the drug interdiction programs that are in place or whatever the programming requirements for the offender may entail.
In addition, and very fundamental to the TRA process, is the security intelligence officer information. They're our eyes and ears on the ground in an institution and they're in tune with what is going on in terms of our inmate sources and providing us with information to assess in terms of drugs coming in, who may be involved, who may not be involved, and that sort of thing.
In addition, we review our offender management file for prior urinalysis test results. If we have an offender who has had a random urinalysis test and the result has been negative versus positive for cocaine or another substance, that's a factor in the threat risk assessment in terms of the current application or the current visitor at the gate waiting to come in.
