Mmm, yes, because locking people away and throwing away the key has worked out so well for us so far.
It'd be a waste to bar him for the 30+ he's probably going to get, and sticking around in there with the possibility to get out earlier is only going to hone his already wide range of talents. Chances are he'll just get out more knowledgeable and do the same stupid **** again.
Regardless, sounds like the kid might be a paranoid schizophrenic based on how long and hard he's been running. Doesn't really excuse the damage he's done, but personally I'd rather someone try to confirm that and possibly treat it, then get his brain working on something productive. Least then he can actively pay back the huge bill he's going to be handed.
