Pentagon workers tied to child porn

A separate case involves a contractor working at the National Reconnaissance Office, the agency that builds and operates the nations spy satellites. The individual admitted in 2008 when he was being interviewed to renew his security clearance that he viewed child pornography at least twice a week on his home computer.

As of December, the individual had been transferred to an agency field office in New Mexico and had not been charged. A National Reconnaissance Office spokesman, Rick Oborn, said he was aware of a few cases of agency employees accessing such images but could not immediately say whether the particular contractor was still working for the organization.

Specialists in child protection expressed alarm at the revelations, but said it was not that surprising to find even officials in sensitive government positions engaging in such activity.

"Some are in high-ranking positions, in positions of trust," said John Sheehan, executive director of the exploited child division at the National Center for Missing and Exploited Children, which has been consulted on many of these cases and has reviewed 36 million images of alleged child pornography since 2002 at the request of law enforcement agencies. "There isn't a profile or stereotype, which makes it even more challenging for law enforcement."

The Pentagon's investigation reports show that personnel found frequenting the illegal websites worked at a variety of Pentagon installations.

Thirteen suspects were identified in California, including individuals who worked at some of the most sensitive military installations on the West Coast. One was a contractor at Edwards Air Force Base, where weapons testing is conducted, while another worked at the Naval Air Warfare Center at China Lake.

Their positions gave the cases priority at the immigration and customs agency that first uncovered them, according to the reports, "because the subjects are DoD employees who possess security clearances."

A large amount of pornography was found on the office computer of a program manager at the Defense Advanced Research Projects Agency, including images that appeared to be of children. DARPA is responsible for developing some of the military's most secret weapons and technologies. Charges were not pursued because there were no images of known victims of abuse, something that is routinely needed to bring charges, the case summary said.

A DARPA spokesman, Eric Mazzacone, declined to comment.

Other agencies where personnel were investigated are blacked out in the documents because their jobs were so highly sensitive, including a case from 2007 in which a national security official had 93 documents, 8,400 pictures, and 200 movies "that were evidence of receipt of child pornography." The individual was sentenced to five years in prison and five years of supervised release.

Others have not led to criminal prosecutions, such as the 2007 case involving an employee at the Defense Contract Management Agency in Hartford who had about 40 images believed to constitute child pornography on a government-issued computer. The individual was not prosecuted because the ages of the individuals depicted in the images could not be determined or positively identified as known child victims, according to the reports.

Another case opened in August 2007 involving a Defense Department contractor was closed "due to a lack of resources," a November 2009 report from Pentagon criminal investigators said.

The case was referred back to Immigration and Customs Enforcement.
