As we have seen, Brenda Leyland, an intelligent and highly educated woman felt 'entitled' to indulge her pastime of excoriating a family from a neighbouring village who had suffered great misfortune.
Like all poison pen writers she was anonymous, she knew who her targets were, she knew where they lived, I would be very surprised if she didn't know where the kids went to school but they knew absolutely nothing about her or her activities.
In my opinion Brenda Leyland's online activities and her location (from her IP address) should have raised official concern ... and who is to say that Martin Brunt didn't recognise that by starting the Sky news investigation at the centre with the intention of working out?
However if it had all been nipped in the bud many years ago and the culture challenged I think there are many who would think twice about the risk of having the police knock at the door and I think Brenda Leyland would have been one of them.
