Thank you.
There is a volume of evidence, most of it from south of the 49th parallel, the United States, that makes it very clear--and it's very convincing--that where you identify the recidivist, the serious offenders, the people who keep committing crimes, and you lock those people up for as long as possible, the concurrent precipitous drop in the crime rate is clear and convincing. That's not currently the way our sentencing parole regimen works. We can't quite get there yet.
I guess what I'm telling you is there is a volume of academic research that says when you put those offenders in jail for extended periods of time, the crime rate generally goes down.
