Preston has never asked for anyone's sympathy or understanding about his past crimes. If you read his stuff, he owns it fully, is incredibly sorry. He's the first to admit that what he did had very real consequences.

What good are we doing to society if we are keeping rehabilitated individuals locked up at taxpayer expense? There's no objectively correct amount of punishment. The correct amount of punishment should be the smallest amount of time necessary to be confident that the criminal won't cause more harm to society, especially when the crime was committed as the result of a treatable illness like addiction.
