Q. Nobody said anything was inadmissible. It was decided not to go forward with them. If he had been found not guilty then the further charges would have been considered, as was the case with Dave Lee Travis. He has a booking with the courts shortly. I have issues with this approach in general and if for no other reason than blocking up the courts, CPS should be given everything the police have on a person and decide whether to prosecute once, unless further evidence is forthcoming.

Being in possession of images of under age children in sexual activity or nudity posed for sexual attraction is in itself an offence. You can argue that you tried to download only adults and this came as well but it is up to you as the person in possession of illegal content to explain your lack of intent.

I really can't understand your question. You keep quoting foreign law and precedents but they have no bearing whatsoever. Incidentally, many prosecutions here were on the basis of FBI handing over credit card transactions of UK citizens paying for child porn where FBI had raided the source.
