"In 2006, the Immigration and Customs Enforcement agency, which conducts Internet pornography investigations, produced a list of 5,200 Pentagon employees suspected of viewing child pornography and asked the Pentagon to review it. But the Pentagon checked only about two-thirds of the names, unearthing roughly 300 defense and intelligence employees who allegedly had viewed child pornography on their work or home computers.
The defense investigators failed to check an additional 1,700 names on the list, defense officials have revealed in correspondence with Senator Charles Grassley, Republican of Iowa.
Acknowledging the lapse, the Pentagon has told Grassley that child porn investigations were not a high priority at the time of the Immigration and Customs Enforcement investigation, and that it is now checking the additional names.”
This was revealed 3 years ago and no action has been taken since.
