A final report on the gunwalking scandal known as Operation Fast and Furious shows a Homeland Security agent in Arizona participated in the operation and tried to warn his superiors in Phoenix, but those officials never read the reports.
The report was written by the Office of Inspector General, which investigated Fast and Furious. It shows that agents in the Bureau of Alcohol, Tobacco, Firearms and Explosives tried to keep rival agents in Homeland Security from discovering they were letting guns into Mexico.
The breakdown extended even further. The OIG found that one Immigration and Customs Enforcement agent working with the ATF tried to tell his superiors about the gunwalking, but his reports were never read.
As a result, the Inspector General concluded that senior Homeland Security officials in Washington did not learn of the gunwalking operation until after one of its agents, Border Patrol Agent Brian Terry, was killed in December 2010.
