DOJ, FBI Target Child Porn Sites on Dark Web

A joint effort between the Justice Department and the FBI has led to the conviction of 18 men and the dismantling of four dark websites dedicated to images and videos containing child sexual abuse material.

The websites shut down by Operation Grayskull attracted more than 120,000 members, included millions of files, and garnered at least 100,000 visits in a single day, one FBI official told CBS News.
