Shame that Kate writes in 'madeleine' that the sequence of events was quite different. I will dig out the relevant cite, yet again, for anyone who wishes to be pedantic.
Kate wrote MADELEINE with personal experience and the benefit of hindsight. I would therefore expect whatever she writes to be much more accurate than a newspaper not in possession of all the facts as she was.
However the gist of the article is all to accurate and that is that the McCanns were made arguidos eight days before a change in the law meant that mere suspicion of wrongdoing was not enough justification for so doing - it required firm evidence in justification.
In my opinion a disinterested observer looking at it dispassionately would be able to see at a glance why the law was changed ... it made mistakes less likely and cut down on corruption.
So fire ahead ... I think pedants are always welcome ... they certainly used to be on this thread.
