My last question, if I have time, is for Mr. Hutton.
You were asking why we wouldn't just do the other community-based.... What's the answer to the question? What constraints would there be to having more community-based, contact-based supervision? Is there a reason to use electronic monitoring because there are constraints on what, according to research, appears to work better?
