steve, the vote that George B gave the families was done BEFORE the offer. Once the offer was on the table, he should have given them another vote. 

And it WAS possible for red to get DP. 
We do not know the real reason why the one person opposed it. It COULD have been that they opposed DP for all, but it could equally have been that they preferred that red gets the manson or possibly the dahmer treatment. 

As to the manson family, they have been BEGGING to be out. They are no longer threats to society, but we continue to keep them in there and let them die in prison. Im good with that. 
And most ppl who have been sentence to life in prison at a young age, and then put in a place like ADX have BEGGED for DP. Some have attempted to kill others to try and force the issue. Attempted suicide is very hign amongst the group. 

So, I would argue that there is PLENTY of proof to back that up.
