I believe that from the very beginning of this fact finding mission, Le interrogated Kc and based on the questions they asked and didn't ask, they had no idea whatsoever what had happened. They were even accusing her of lies based on everyones misconception of the date June 9th.
Since then it has been the same thing. Everyone is looking at every angle and suspecting every person because no one and I mean no one really knows what happened here. Many believe that the evidence points to Kc, but there is no real rock solid physical evidence, and most circumstantial is after the crime and not leading up to the crime.
The A's clearly have no idea what happened here. That is why they are speculating and hope the Le investigates everyone including Kc. I think because Le has the right to look into suspicion (when they are not sure), everyone else has the right to look at anyone that looks suspicious in anyway.
Until there is some rock solid evidence, then we should all be looking at other options. That includes many others. Currently Rk is the one with circumstantial evidence making me suspicious. I tip my hat to Le for looking into all these people and hope they continue to do so, I also tip my hat to the defense for pointing out that they missed some stuff with Rk. There is nothing wrong with constructive criticism . I am sure Le welcomes it, and I really do believe Le would love to investigate Rk again. Investigating is what they do, and I am sure they enjoy it as much as I enjoy my job.
