Anthony Mangione, Immigration and Customs Enforcement in South Florida, pleaded not guilty to child porn charges in federal court Wednesday, the Associated Press reports. He was indicted for "charges of transportation, receipt and possession of child pornography," which would carry a penalty of up to 20 years in prison. Mangione, who has headed ICE's Miami office since 2007, has been on paid administrative leave since the spring, the Associated Press reports. The New York Times' Lizette Alvarez reports that Mangione was "aggressive" in fighting peddlers of child porn, saying in 2009, "Too many children are victimized by predators that target the most vulnerable among us -- our children." Interestingly, the FBI's press release on Mangione's arrest does not mention that Mangione worked for the government.
