May I build on what Tara said a moment ago? It's early days in regard to our understanding of how well drug treatment courts work. To the best of my knowledge, we have not had a thoroughly methodologically sound evaluation of drug treatment courts that rises to peer-reviewed levels. What we have are indications of promise in some circumstances. But here's the larger problem. When we're talking about drug treatment courts and drug abusers, we are also talking about people with pre-existing mental and psychological conditions. One of the many problems with this bill is that it does not comprehend the context in which it proposes to punish people. It does not take into account the fact that some of these people have pre-existing psychological disorders that they use drugs to treat.
I'll return to some other aspects later, but I want to give Richard a chance to speak on this.
