super creepy fact: JMC was a teacher's aide at my school.
That aside, I really struggle with the motive for John or Patsey to cover up anything for one another. That's what's missing for me—big time. Spouses, while loyal to an extent, most likely wouldn't help cover up the murder of a child or family member unless something major was at stake.
lets assume Patsey did it in frustration. I understand why she would cover it up herself, why she would want to protect her own image, but I don't see that with John. Unless she woke him up & said Jon Benet was missing & said nothing else, I can't fathom him being a willing participant solely to cover Patsey's ass.
Burke was what... About 7-10 years old? I'm not sure (unless the theory of him being involved accidentally) he'd really have enough recall to give any new info, unless her were to speak about what his parents said over the years. He was young enough that growing up, even if a parent was guilty, there would've been plenty of time to have a child genuinely believing a different version of events. He, thus far, remains out of the public eye & frankly, were I in his shoes, I wouldn't be courting the press either.
