Kane's real point is that if the Ramseys truly believed an intruder killed their daughter, they would not have let Burke out of their sight. Since they did allow him to return to school, Kane and LE thought this reinforced what they themselves thought happened the night of the murder: one or the other parent killed JonBenet. Thus, the parents knew Burke was safe.

In other words, Kane was still trying to pin the murder on the parents. He went to Atlanta with no other intention. He was not about to discuss newly developed evidence with the prime suspects. Kane had no intention of sharing information nor of brainstorming.

His Great Atlanta Fishing Caper was a bust.
