My children (12 & 10) went to the park yesterday on their own. The park is situated just down the road from their grandparents who I called just to say they were in the vicinity so to keep any eye out for them. My eldest, who is very sensible, (she is at that age now where she likes to go to the cinema etc with her school friends with no adults in tow!
), had her phone and I gave her strict instructions on taking care of herself and her younger sister. We live in a nice neighbourhood and it's generally a very safe place for children to be out and about. Nevertheless I made sure they both understood the importance of being mindful. I actually think I was perhaps a little too over concerned. My wife later walked around to her parents, checking in on the children who were fine and having fun with their friends.
The McCanns left their very young children unattended in an unlocked hotel room in a foreign country whilst they went out on the piss. Yes, they are bad parents. As others have said, had the McCanns being anything other than two white, wealthy, professionals they would have been dragged through the mud by the press and at the very least both been charged with child neglect.
As for what I think about Madeline's disappearance? I believe that it was a case of accidental death and the McCanns' covered it up and then called in some very powerful friends in high places to help cover their tracks. If we can believe that a group of rich and powerful people can cover the tracks of a monstrous paedophile for over 30 years then we have to believe the probability that others in positions of power are capable of protecting the McCanns.
