CBS News has learned that the Mexican Government has retained an American law firm to explore filing civil charges against U.S. gun manufacturers and distributors over the flood of guns crossing the border into Mexico.

On November 5, 2010 President Felipe Calderon expressed his frustration to CBS News correspondent Peter Greenberg: "We seized more than 90,000 weapons...I am talking like 50,000 assault weapons, AR-15 machine guns, more than 8,000 grenades and almost 10 million bullets. Amazing figures and according to all those cases, the ones we are able to track, most of these are American weapons."
