It was reported earlier this week that the FBI won a great victory by stopping the largest child porn distributor on the Internet. The FBI's victory lap was cut short when some of the details of how they did it were more closely examined.
What the FBI actually did was seize a hosting service on the hidden TOR Network. The owner of the hosting service Freedom Hosting was not directly involved in the production or distribution of child porn, he just provided anonymous hosting used by pedophile pornographers.
The bigger question became how the FBI penetrated the supposedly anonymous TOR Network. That's where the story gets interesting.
