Yes, there is, and part of that involves an interview and an assessment by the witness protection coordinator. Only the person who is actually trained in that field will undertake the final decision.
We have a number of people who are informants and who want to come forward and volunteer to be a police agent, but a lot of those people are screened out for a number of different reasons. When we do use an agent, that situation normally involves a lot of police personnel, and it's usually one fairly high-level targeted operation. We only have the capacity to run a limited number of these operations at a time. We try to be as careful as we can with the people we bring into that agent status, because we want doing so to be to our greatest benefit.
