I agree with the first part of your comment. He seemed to agree with the "You don't belong here" comment, which I disagree with. Do the crime, do the time. "What a waste" was a bit more accurate -- a waste to have him in jail, and a waste to have so many people in jail overall.
That said, your 2nd point is incorrect. He specifically mentioned working to reform MO prison statutes -- albeit, without consulting corrections officers.
