I'd appreciate it if you could provide that. I think that would give us a good sense as to what the success of the treatment is and how big an issue it is when offenders choose to pull themselves out of the treatment. The accountability, as you mentioned, has to be there. They have to understand the need to help themselves as well.
There's one last thing I wanted to touch on: our strategy in terms of dealing with drugs in the prisons. There are a lot of good things that were recommended in the transformation agenda and a lot of good things that the Conservative government has put in place to help create a zero tolerance situation for drugs in prisons. I'm wondering if you could give me some examples and statistics of the success that has been created by some of those measures our government has put in place to deal with drugs in prisons.
