He is being defended from the suggestion that he had anything to do with sex attacks on the Algarve, despite the fact that he lived there and is a known paedophile - why is that?
I think it is called being accurate.
When he was picked up, he had been living in a camp site in Olhão (eastern Algarve) for 2 months, if the camp site owner can be trusted.
To be accurate, I don't know precisely when he entered the Algarve, though from memory he was tracked because he bought and drove a motor home from the UK to Portugal. I think that was shortly before he was picked up here.
He seems to have spent a considerable number of months in Lisbon prison before the deportation came through.
So, he's in the wrong area of Portugal at the wrong time. Plus there is nothing to suggest that he was in Portugal for the period spanning 2004-2010.
Other than that, we appear to have one source concluding from this that he was living in the nearby area when Madeleine disappeared.
Take your pick.
