This paper also briefly describes the training and technical assistance provided by the following organizations: Fox Valley Technical College; School Resource Officer Standards, Training, and Technical Assistance; and Law Enforcement Technology Assistance. Also described is the capacity-building provided by the Internet Crimes Against Children Task Force Program, which provides training to law enforcement agencies and prosecutors in the investigation and prosecution of online child pornography and child enticement cases.
