Why shouldn't he get 50? What do you think he will get?
He should get 100 for all I care. I just know/suspect the legal maneuvering already taking place will try to whittle it down some. Some sort of plea agreement, "donations" etc to get it down to 25+ years or so.
I hope they throw the book at him, but I'm sure a lot of deals are being worked on to try and reduce as much as they can get by without a costly trial/attention etc.
