It's not hindsight to say it was not a good idea to leave children alone with doors unlocked before, since and during 2007.
You agreed with this. So why is it hindsight?
I am confused by the double negative in your post which makes it appear to mean the opposite of what I think you intend.
But I don't believe I have ever stated what you claim whichever one of the options is correct.
The hindsight relates to the fact that there is no allowance made for the fact that it was a normal practice prior to the disappearance of Madeleine to use visiting services in holiday destinations/resorts. There is nowhere that I can find any outcry whatsoever against the practice prior to that disappearance. It is only with the benefit of hindsight that this is now considered to be wholly unsafe.
It is, in my view, wrong for posters to suggest that what the McCanns did was against common sense, was neglect etc. when at the time they did it, it was in fact a relatively common practice. It is only with the benefit of hindsight that we know that to be the case.
If you or anyone else can show me to be wrong and give links to any outrcry about such visiting services prior to the disappearance of Madeleine McCann I will read them carefully and am prepared to change my opinion.
I would also repeat here my request to Redblossom regarding the statement she made that some organisations still operate such schemes. I would like to see details of these organisations and schemes, please, because I now believe that they are unsafe and would like to write to them expressing my concern. Unfortunately, even though I indicated that this was an urgent request as we are already in the school holiday season, she has chosen to ignore me. I hope she wasn't just posting this claim for some kind of effect and that she will get back to me very soon with the names of the organisations.
