As sad as I am for the McCanns, I wouldn't consciously do what they did in a foreign country and leave my child alone. However after a few drinks and in a nice environment, I might have had a warm feeling that this place is so nice and the people so friendly, there is no need to worry. I don't accuse them of neglect. They were just extremely unfortunate that this happened to them. Having spent many summers in Spain on holiday with a Spanish family, which is not that different to Portugal, I would say that living in south London is completely different. You may pick on DM for her views but ask yourself what would you have done in similar circumstances.
