Shame on his parents

In case you missed it, earlier this month 15-year old Shawn Hornbeck returned home after being kidnapped four-years earlier.

For reasons I still don't understand this kid has been paraded through press conferences and the Oprah show. What is wrong with his parents? Why, after Hornbeck has endured years of hell, would they do that to him? What was achieved by having him interviewed by Oprah? Am I the only person that finds their behavior slightly appalling?
