A federal operation that allowed weapons from the U.S. to pass into the hands of suspected gun smugglers so they could be traced to the higher echelons of Mexican drug cartels has lost track of hundreds of firearms, many of which have been linked to crimes, including the fatal shooting of a Border Patrol agent in December.
The investigation, known as Operation Fast and Furious, was conducted even though U.S. authorities suspected that some of the weapons might be used in crimes, according to a variety of federal agents who voiced anguished objections to the operation.
Many of the weapons have spread across the most violence-torn states in Mexico, with at least 195 linked to some form of crime or law enforcement action, according to documents obtained by the Center for Public Integrity and The Times.
The Bureau of Alcohol, Tobacco, Firearms and Explosives, which ran the operation, said that 1,765 guns were sold to suspected smugglers during a 15-month period of the investigation. Of those, 797 were recovered on both sides of the border, including 195 in Mexico after they were used in crimes, collected during arrests or intercepted through other law enforcement operations.
