At the Center for Missing and Exploited Children, a clearinghouse for online pornographic images of children, 50 analysts screen between 100,000 and 200,000 image and video files. Working with Internet providers and the public, they help law enforcement officials keep up with the movement of these files.
"[Pedophiles] take these images and trade them like baseball cards," says Christine, an analyst. "The violation that occurs within these files...it's horrific."
What they see on a daily basis is so disturbing the center keeps an on-site psychologist to help analysts cope.
"We're seeing sexual abuse including oral penetration, vaginal, anal penetration," says Michelle, another analyst. "We see children with dog collars on their necks. Kids with plastic bags over their heads. Foreign object insertion with these children."
