Homeland Security Chief Janet Napolitano told U.S. senators conducting Judiciary Committee hearings Thursday that she was not aware of her agency's controversial involvement in an ATF operation that let guns reach Mexican drug cartels.
During an operation called "Fast and Furious," the Bureau of Alcohol, Tobacco, Firearms and Explosives allegedly intentionally allowed numerous weapons to fall into the hands of Mexico's drug cartels. Law enformcenent insiders call it letting guns "walk."
An agent from U.S. Immigrations and Customs Enforcement (ICE) was apparently linked to the operation, CBS News has reported.
Two AK-47 variant rifles that ATF had recorded as having let "walk" nearly a year before were found at the murder scene of Border Patrol Agent Brian Terry in December.
