Washington, D.C. ? The Department of Justice released its first-ever national strategy to combat child exploitation and abuse Monday, which calls for a crackdown on the most dangerous sex offenders in the country.

The National Strategy for Child Exploitation Prevention and Interdiction will assess the threats that children face — including child pornography, online enticement, child sex tourism and commercial sexual exploitation — and outline ways for the federal government to quell abuse.

Part of the strategy calls for the U.S. Marshals Service to launch a nationwide operation to target the 500 most dangerous, noncompliant sex offenders.
