It's the ultimate movie-plot threat: terrorists using child porn:
It is thought Islamist extremists are concealing messages in digital images and audio, video or other files.
Police are now investigating the link between terrorists and paedophilia in an attempt to unravel the system.
It could lead to the training of child welfare experts to identify signs of terrorist involvement as they monitor pornographic websites.
Of course, terrorists and strangers preying on our children are two of the things that cause the most fear in people. Put them together, and there's no limit to what sorts of laws you can get passed.
