I think there is a significant challenge for the staff. It is a balancing act in terms of dealing with those individuals who are prepared to address their problems, the problems that have brought them into conflict with the law, and in this case problems with substance abuse, versus those who continue to be involved in an underground economy, a criminal activity, within the institution.
That's one of the reasons why we've structured ourselves around that three-pronged approach. It allows us to have the capacity to help those who have come to a realization that they need to get their lives in order. They want to participate in programs and they want to change things around. At the same time, we have the capacity--with, for example, Mr. McLauchlan, security intelligence officers, our drug-detector dog teams, even our front-line correction officers--to deal with those who are still actively involved in criminal activity or are bringing drugs into the institution.
So it is an ongoing balancing act, at times more challenging than at other times. Mr. McLauchlan can talk about some of the significant challenges coming from an institution where there are significant aboriginal gangs who are constantly involved in trying to bring drugs into the institution.
