The government has little say in what happens to inmates inside the prison system. They were notified of the transfer.. not involved in it happening.
They can go on about creating new laws and such to keep him in max security.. but I think the charter and courts will put a damper on whatever they try to do.
Mixed emotions on P.B. It's different for the families that are directly involved as closure is a sensitive issue for them.
For me, he needs to be locked up for life. If medium security saves the taxpayer a buck or two and keeps him locked up I'm OK with it as long as he doesn't start living in Club Fed.
As far as security goes, P.B. should feel safer locked up. There are people that would like to meet him in a dark alley should he escape. There would be no shortage of volunteers with pruning shears.
