The Dept. of Justice (DoJ) reports that online child pornography crime has increased. DoJ funds the Nat. Center for Missing and Exploited Children (NCMEC), which maintains the CyberTipline to receive child pornography tips. A law passed in 2008 contains provisions to facilitate these investigations and create a national strategy to prevent, among other things, child pornography. This report examines: (1) the extent to which NCMEC determines the usefulness of tips; (2) mechanisms to help law enforcement coordination (i.e., deconfliction); and (3) the extent to which agencies are addressing factors that federal law enforcement reports may inhibit investigations. Includes recommendations. Charts and tables. This is a print on demand report.
