You're ignoring the most fundamental assumption of the American criminal justice system. The presumption of innocence.
You also miss the lesson that can be learned from the article. If prison is treated as rehabilitation criminals can change their path to go in a positive direction. What your comment supports is the idea that consequences have permanent and devastating consequences on future potential. This is an attitude that hurts everyone.
Your last paragraph makes no sense to me. Presumably the truck driver is breaking the law and should go to prison?
