A high-risk offender will be met with frequently by a parole officer in the community. Somebody who is on statutory release with residency will be living in a halfway house, so they'll be interacting constantly with our staff. That interaction is going on all the time.
I think what you raise is a really important empirical question. If we do increase that interaction, could we get an effect? The problem is that most of the studies that have been done in the past haven't used the GPS technology we're talking about. It was used mainly for house arrest, conditional sentencing, and things like that. The increase in opportunities for positive interaction, those interventions, was not really part of those studies. There is a possibility that in the future we will see a positive impact.
One of the things you have to understand about electronic monitoring is that it doesn't last for a long time. In a number of studies I looked at, the period of electronic monitoring ran for 13 or 14 weeks, so it's not a permanent disposition. There are longer ones that may range up to three years, but the average is 13 to 14 weeks. You actually wouldn't expect an intervention that lasts such a short period of time to have a major impact.
If someone has had a crime lifestyle lasting 10 to 15 years and you put him on electronic monitoring for three months, you're not going to change his behaviour, but it's one piece in the package and it gives us one opportunity for some additional interaction with the offender.
