Well done the security services capturing and prosecuting him, though he does not sound like a major terrorist.
The materials that the Mail says he had are not illegal, and freely available to download by anyone.
And to carry incriminating evidence on his person is just stupid.
But being a member of a terrorist group is illegal and that will get him jailed. The James Bond cufflinks is just fantasist drivel by the reporter.
I have already said, many times and again earlier today, that I deplore any acts of terrorism by anybody, no matter who is responsible, so why are you still blathering on ?
