Sorry, Angelo, what I found funny was the "slow" detail !
Dave Edgar suggested it shyly because all sorts of dangers were to be expected in a lawless region.
Good point Anne, former Ulster detective Edgar did suggest that Madeleine could be held in some sort of a cell in the surrounding area. Where the heck did he get the lawless label from? Isn't the PdL area supposed to be one of the friendliest areas in the Algarve?
Angelo mentions the multiple disciplines involved in searching for a missing child. Indeed, one of the most important is to gain the trust and respect of the locals. This is probably where the SY investigation will fail, police end up antagonising the local population.
If you can carry the locals with you, you end up tapping into a huge resource of who's who and a grapevine of connections which the police will never unravel. We have all heard why Robert Murat's mother set up her mobile information desk. She knew only too well that the people would not confide in the police.
