I seriously doubt anyone, at the time, knew CO law so well. Or would have been confident enough to think that relying on silence would work so well. But even if they did, there is no way a parent would cast away a child who had just murdered his sister! First, because this just isn't parental behavior. You don't abandon a child when something so potentially emotionally damaging happens to them. Second, they had to monitor his communication themselves. If he talked, the ruse was over....they would never be able to follow this supposed plan of keeping quiet and letting the CO law do it's thing for them.
No, I think the most likely explanation for separating Burke from them so quickly and without fear is because they knew he knew nothing. Otherwise you would never trust a child out of your sight. Also, I suspect they wanted him away so he wouldn't hear what they had to say.
As for JMK, you're implying she flew a man to CO based on a lie. Not just any lie, either...a lie to cover for John and Patsy, a lie that completely goes against her oath of office. A lie she told to the public, the public she took money from to bring someone she knew was innocent to the States to begin an investigation she knew was a lie. All for John and Patsy
I don't buy it, sorry. I just don't think John and Patsy were that important to her and I don't think she is that corrupt.
