Great resource, especially if you have children who use the Internet.

Cyberangels (an all-volunteer group) has been best known through the years by its work cooperating with law enforcement in locating online crimes and criminal content, such as child pornography, predators and stalkers, and helping train law enforcement about online search and investigation methods.

Using knowledge of online harassment and crimes, Cyberangels has long aided law enforcement in finding child pornography, sexual predators and other online criminal content and activities. The U.S. Customs cybersmuggling unit alone is arresting one online predator or child pornographer every other day in the U.S. Many of those cases involved Cyberangel help.
