The John Mark Karr story was fishy from the start.
Let's see....You've been arrested in Thailand (where the prisons are not very charming) and you need a foolproof escape plan.
You are a complete pervert kook obsessed with the Ramsey and Klaas cases.
You need to get the hell out of Dodge, so you admit to the Ramsey killing, even though you were never in Colorado during any Xmas in the '90's.
Voila! Lots of face time on international media, business class trip to LA, then on to Boulder, where you know that you won't be charged because you didn't do the crime!
What we need here is a little "Jailhouse Justice*", if you know what I mean.
Next prediction, Karr contests extradition to California to face his child porn charges.
* I'm pitching "Jailhouse Justice" as a Reality TV Show for the new CW Network.
