Lifetime detention for misconduct at age 14?

When he was 14 years old, Daniel Arends made a big mistake. He sexually assaulted an autistic boy. He was adjudicated as a delinquent. Then, he made some other mistakes. His juvenile detention was extended several times for sexual contact with other boys. When he turned 17, he learned just how much trouble he was in. He became the first juvenile that the state of Wisconsin sought to detain indefinitely under its "Sexually Violent Person" civil commitment law. He was committed to the Sand Ridge Secure Treatment Center in 2005, and he has remained there ever since.

He is now 22. Technically, there is a way for Daniel to get out of this potentially lifelong incarceration. All he must do is show that he has changed so that he no longer meets the legal criteria of being "more likely than not to commit a future act of sexual violence." The Catch-22 is, how can one prove something like that from behind bars?
