There are people out there in law enforcement who's job it is to collect child pornography, categorizing and filing it in the hope of identifying the victim and the perpetrator. When there is a breakthrough and the child gets saved, these people are the heroes that make it happen. However I imagine that for every perp caught there are a dozen more that escape justice... personally I can't imagine doing such a job - it'd tear me up inside to know these people are out there. But someone's got to do it.
