Recently there were a few large takedowns of child-pornography networks in Canada. Pick one and discuss who the members were, how they established trust and communicated amongst each other. Focus on the specific methods employed by them to hide their activities, and how law-enforcement was able to break into the network and collect enough evidence in order to take them down. Review the literature on police operations against child pornography, and situate the specific attack you chose within that literature. How does this attack compare to others reported in the scientific literature?
