Weapons Traffic: Agent: I was ordered to let U.S. guns into Mexico

Agent: I was ordered to let U.S. guns into Mexico - CBS Evening News - CBS News: "ATF agent says 'Fast and Furious' program let guns 'walk' into hands of Mexican drug cartels with aim of tracking and breaking a big case.

Federal agent John Dodson says what he was asked to do was beyond belief. He was intentionally letting guns go to Mexico? "Yes ma'am," Dodson told CBS News. "The agency was."

An Alcohol, Tobacco and Firearms senior agent assigned to the Phoenix office in 2010, Dodson's job is to stop gun trafficking across the border. Instead, he says he was ordered to sit by and watch it happen.

Investigators call the tactic letting guns "walk." In this case, walking into the hands of criminals who would use them in Mexico and the United States.

Agent Dodson and other sources say the gun walking strategy was approved all the way up to the Justice Department. The idea was to see where the guns ended up, build a big case and take down a cartel. And it was all kept secret from Mexico."
