I don't have the IT schematic in front of me, but that was just one example of how a sophisticated network can do a drug transaction. One of the duties of the security intelligence officer is to deal with drug interdiction. Each item that I deal with can be unique. In some cases, it's as simple as an inmate knowing that he has violated his parole and putting a small amount of drugs into his rectum, so that when he's returned to the institution, he'll have something for his personal use.
Sometimes the things we're dealing with are as complex as the chart you have before you, which can involve a middleman. It can involve multiple people buying drugs, drugs coming from multiple sources going into different areas, being packaged by different individuals, and then distributed to other individuals to bring into the institution. Once they come into the institution, there's a distribution network within the institution. A drug transaction can sometimes be very simple and sometimes it can be very complex.
We use the tools and the training we've been provided to try to.... If we can get a line on one aspect—perhaps we intercept a communication with regard to one person—then we'll start an investigation, which can expand from there, and perhaps we'll be applying for authorization to intercept additional conversations. Perhaps we'll monitor some individuals by video. It could involve liaising with our partner agencies in the criminal justice system: for instance, involving the police forces with regard to things that are going on in the street.
What you're seeing before you is an example of a very complex transaction, and sometimes it's everything in between.
