If CB's responsible for HB's rape, then I hope of course that the evidence HCW has is sufficient to bring charges.
If CB's
not responsible though, I hope the evidence HCW has allows room for that too since no one gains by an 'it must have been CB' conviction, least of all HB.
Is that actually a working conspiracy?

It's nonsensical, if so. That a professional police force would engage with let alone embark upon such a smoke and mirrors path, putting its reputation on the (international) line, is just ludicrous. Apart from which, HCW has never seemed to have had much interest in or regard for the McCanns one way or the other since his is specifically a murder investigation, which has no parallels with the past investigations.
I agree broadly with your post @#124. Are you surprised by this update? I'm not.
