I'm not so sure it's a good idea. This is where I depart from my friend. I never thought it was a great thing, other than to try to put some pressure on the judge, even on the adult side.
If you rob a bank and you get convicted and you're sent to prison for eight years or whatever the term might be, and I think I might rob a bank too, I'm not being deterred by the fact that you're there. I can say to myself, I'm smarter, I'm not going to get caught.
So I don't think that deterrence, in a general public sense, is very much. Personally, for the offender, deterrence might have some effect, but the very fact that he's being dealt with is enough deterrence. I don't think you need it.
