What exactly about his oxycontin use was *criminal*? Do we hold to absolute values? -- The Founder's Natural Rights doctrine also implies absolute "natural" values, that is that there are acts which are criminal, by their very nature.

What is *criminal* is holding people to harsh account for acts which by Natural Rights are not criminal!
I dunno, lets ask all those folks with drug convictions on their record.
