Court documents last fall revealed that the FBI secretly operated and controlled a large proportion of all child porn sites in the United States. See here.
Further investigation has revealed that the FBI’s control and operation of the “child porn industry” was much greater than previously admitted. Through the FBI’s “Operation Pacifier,” the FBI published untold thousands of child porn images–including images of child rapes. See here.
The stated purpose, of course, was to capture and prosecute (nongovernment) people who surf the secret government websites.
