It can do a world of good for offenders who want the help. Let me quickly tell you, my brother-in-law is a lifer; he committed first-degree murder. He was eligible at 15 years with a “faint hope”. The two people he was co-convicted with, who were much more seriously involved in it than he was, got out at 17 years. He stayed in another two and a half years, because he thought the system had more to offer him. He's out and he's working as a chef at a golf course now. I speak to him a lot about this. He says for those who want it, it is there. But that's not the majority of people.
So sometimes that extra time can be extremely beneficial.
