Yes, that is what I suspect, that his DNA was ALL OVER the crime scene but since he was 9 years old, he was protected from prosecution. Then I ask myself, "If John and Patsy knew that, why did they go to such an extent to cover up the incident?" Maybe they didn't believe their lawyer(s)? Maybe they didn't get a chance to speak with one of the lawyers during the night? Or maybe Patsy knew that Burke would be put into protective custody at least, even if he couldn't be imprisoned. Maybe Burke's psychiatrist had warned her, or told her that Burke was on his way to being rehabilitated, and she was trying to keep him out of the system... I'm wondering if Burke did most of what happened that night. Except for the note, of course, and that can be explained by Patsy coming on the scene in the early morning hours. Burke's question on the phone call, "But what DID you find?" could mean he either disassociated during the crime, or that he was playing innocent and didn't know if they had actually found JonBenet's body. Plus, if Patsy undertook to write the "ransom" note while Burke went to bed, then he would have been confused - he hadn't left any ransom note. The way he reacted to JonBenet's death - as described by Kolar and documented by photographs of the funeral - is not normal. To extinguish his sister from a drawing he was asked to do only a few days after her death? Really shocking. He even discussed the means of her death which at that point, no one knew. Yet he could not be touched through the legal system. If Patsy and John confused Burke by telling him that JonBenet had been the victim of an attempted kidnapping, then he may have grown up believing that he did NOT kill her after all (not that he necessarily even KNEW he had finally killed her) so in his mind, he would have nothing to confess. Thus, people who think Burke should "come clean" are going to wait for a very long time.
