The Justice Department says it’s doing all it can to protect children online. Justin Berry and some congressional representatives don’t see it that way.

Berry is the 19-year-old Southern Californian who testified before a House subcommittee earlier this month, telling the panel that beginning at age 13, he was persuaded by older men to strip and perform sex acts before a camera linked to the Internet. After five years of running his own online child pornography business, Berry had come to the Justice Department with the names and other identifying materials of hundreds of men who had sexually manipulated and abused him after accessing his site. Nine months later, just two of the men had been arrested, and Berry said federal prosecutors placed his life in danger by disclosing his identity in an unsealed court filing.
