No Grahame, Mike is on a 'fishing trip'. He believes ex police officers read the forum and he believes they have things to hide. He hopes that one of them, if they think an ex colleague is about to break ranks, may come forward with information. It's a tactic.
Of course, why did no one come forward with any information when Bamber was offering a million pound reward?
Why show Mike pictures which they were not prepared to be given to the defence, when those pictures would lead to almost instant CCRC action?
Why communicate in a bizarre one sided conversation in open forum?
Do you really believe Sheila could be pronounced dead at the scene, whilst still alive?
