There's a website about this guy:

Seems a little uncoherent, but there's plenty of cool bits of information there.
What I found most interesting is that he had already changed, and was working in a drug rehab center etc before he was arrested/convicted. Makes you wonder whether he should've had that jail sentence at all. Is the purpose of jail to change people (which wasn't necessary for him anymore) or to punish them? (And really, what good does punishment do if it doesn't matter whether the person changes or not?)
Food for thought...
