What the McCanns did was no more than many do, sit in the garden in summer with friends whilst their children are upstairs, asleep (if they have children who sleep).
Anyone can "Tut tut" and say, "I would never have done....", but have probably done or not done other things. I know I said it already but there are some who enjoy being angrily self righteous which achieves absolutely nothing. As for suggesting the McCanns were responsible for their child's abduction - why?
? It beggars belief how peoples' minds work, are they jealous of the McCanns in some way? There's certainly a lot of personal resentment which has nothing to do with sympathy for little Madeline, it has a life of its own.
As to the implication that the McCanns have made money for themselves out of this tragedy, that is beneath contempt. If anyone is unsure where the fund money has been spent, they only have to make enquiries.
The same sort of vitriol poured out on the McCanns apparently often happens in America with high profile cases of child abduction where parents keep the child in the public eye and raise money to continue searching. One particular case springs to mind, that of a fourteen year old girl called Elizabeth Smart who was kidnapped from the bedroom she shared with her sister. Apparently the abductor entered by a route that was usually locked, on this occasion the parents hadn't secured it. One can only imagine the guilt they felt.
https://en.wikipedia.org/wiki/Elizabeth_SmartThere is a quite harrowing but very good book and a film about her ordeal.
The Smarts came in for endless, vicious criticism from the public.
