Just think about it. KAK has been on LE's radar since Feb. 2017. They knew about a_shots, searched all his electronic devices, and interviewed him in less than two weeks after the murders. We don't know when LE became aware of his possible communications with L, but can you even imagine the pressure LE would have put on him if he was not BG, but had basically catfished L just prior to her murder? What are the odds?
