If they weren't named everyone spoken to by the PJ would be under suspicion of being an arguido.
I dont believe they should have been named and the names released to the public.
I would have thought that an organisation as l;arge as the PJ could have devised a system where they took the suspects somewhere else and questioned them in private, away from the public eye
I have never publicly divulged the name of my suspect, despite a multitude of pointers, because i am aware how devastating such publicity, especially in this potential [paedophillic and with global interest] case could be to the man i suspect.
Even in a mundane case, I would never, I hope, publicly point the finger at the culprit.
Apart from the awfulness of accusing someone, I am grounded enough to know that I could be wrong, despite all the scores of pointers.
PS This suspect of mine has never, as far as i am aware, been suggested on any other forum
