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.
