Not sure on that when you read of so so and downloading images some one put them up and its not by accident they are found is it? I don't genuinely know and I'd be surprised if any one on here knows.
We are drifting way off-topic, so I'll keep this brief.
SIS (security service) year 2000 report. 4 main centres of paedophilia in Portugal. 3 international rings operating from Portugal.
Casa Pia - news broke Sep 2002. High profile trial underway when the McCanns visited Portugal.
Aug 2005 - about 209 paedophiles in prison in Portugal.
Oct 2007 - 80 people arrested across Portugal as part of Operation Predator. This may or may not be considered a 'gang'. They seemed to be accessing photos via a website run by citizens in the US, and the US end was also called Operation Predator.
Portugal only quite recently introduced a paedophile register. It was not even on the statute books in 2007.
One of the Portuguese dailies has a detailed section re paedophilia. It publishes about 100 articles per year. Only a small percentage of these relate to arrests/trials, and such reports are not limited to Portugal. I'd had as much as I could stomach when I'd gone 2 years back, so no doubt I am missing a lot.
Cites are on ShiningInLuz, should anyone be interested.
This does not resolve the issue of Gerry's phone call.
