Last 4th of October, both the PJ National Director and the Attorney General gave an interview in SIC TV channel, where they stated that 3/4 SY agents had been to the Algarve for a couple of meetings with the Faro PJ Director. So far only a few diligences required by the UK rogatory were carried on, and all involved portuguese people and none implied questioning those persons.
The phone analysis the SY is carrying on are based on the initial PJ logs which were done just weeks/months after the event - at that time it was not possible to take much from those phone information for the reasons recently invoked by the British themselves, there is no way to tag PAYG phones to their owners. What is different now, more than 5 years later????
The Press is just publishing bullocks in order to sell.
P.S. Seven or six years ago, when I traveled to spend a few days in another country, the first thing I would do when arriving at the airport was to buy a SIM card that I could dispose of as soon as I went home. I bet that was what most people did.
Trying to find out who were the people that stayed in PDL by their cell phones is a joke.
