Paedophile rings and the ways they can be tracked, exposed and punished

I saw with shock reports a week or so ago about what was being described as the most serious case of systematic organised paedophilia in Scotland. Another useful link to this story is here.

I just came across a blog post from around the same time as the two media links above in the ever-excellent Spy Blog which takes the writer's usual clinical and detailed look at different aspects of how this case was cracked. It is a very lengthy and complicated article, but will repay the effort to read it in full and [in my case attempt to] absorb it all.
