I have no argument with the M....... handing the dossier to the police. It does however suggest a closeness between the couple and the individuals who compiled the dossier and harassed Brenda before her death, a closeness that the M...... have been at pains to deny. What they shouldn't have done however is either disclose it's contents, or let them be disclosed by a third party, to the media.
Disclosing the details of individuals included in the dossier to Sky would almost certainly have made any resulting prosecution impossible ( how would Brenda Leyland have got a fair trial after her exposure and subsequent vilification in the MSM ? ) but of course by that time I'm sure the M........ ( who don't forget would be the only ones receiving information from SY as it was them who handed over the dossier ) would have known there was going to be no prosecution so forced to do something like giving the go-ahead for one of their minions ( deniability always ) to give it to Sky.

A lot of speculation going on in your post imo Faith. How do we know how many copies of the dossier there were - or whether copies were sent to other people apart from the McCanns?
How do we know that the McCanns had any idea that a dossier was being compiled - until they received it?
I have no doubt that people (probably relatives or close friends) were monitoring the net - and I would expect that in view of the menacing content of some of the posts on there. Forewarned is fore-armed.
How do you know that the people who compiled lists of posts which broke the law ever harassed Mrs Leyland? For all we know their only interest may have been to collect the evidence and they never posted at all themselves.
What we do know (assuming media reports are correct) is that when the McCanns received a copy of the dossier - they quite correctly handed it over to the police - and that is all we know about their involvment at the moment. Anything else is pure speculation IMO.
