Especially when they said they would do anything to help - especially when the said facts remain unclarified.
IMO it obviously had something to do with the timeline - it has never been checked.
You would have thought also the mccs themselves would have wanted to know where everyone was and what they were doing.
IIRC the tapas were not all known to the mccs - so if the mcs thought an abduction took place you would have thought that everything should have been checked out and not by assuming it was by a stranger IMO.
IMO the only purpose of the reconstitution requested by PJ was to prove that there was insufficient time between checks for an abduction to have occurred, thus adding to circumstantial evidence against the parents. By attempting to prove that their checks were both frequent & diligent, T9 would have actually been adding to PJ belief that no abduction could have occurred - a double-edged sword only pointed at guilt.
We have already learned through the media that CB's lawyer has stated there was only a 90sec timeframe for an abduction to have occurred, meaning his client couldn't possibly have committed such a crime in such a short time.
