"This is a serious violation of international law. What happens if next time they need to introduce trained assassins or nuclear weapons?"

"We who are about to be completely discredited salute you!"

"Mexico angry over US weapons operation."

MEXICO CITY, March 11 (UPI) -- A Mexican lawmaker claims at least 150 countrymen were killed or wounded by guns purchased through an undercover U.S. drug and weapons operation.

Humberto Benitez Trevino, a member of Mexico's Chamber of Deputies, said the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives program called Operation Fast and Furious was responsible and he has called for an investigation, The Los Angeles Times reported.

"We have 150 cases of injuries and homicides with arms that were smuggled and passed illegally into our country," Benitez said. "This was an undercover program that wasn't properly controlled."

The ATF acknowledged at least 195 weapons sold in Arizona under the program were recovered in Mexico.

Mexican lawmakers want to know if Mexican authorities were aware of the U.S. operation.

"This is a serious violation of international law," said Carlos Ramirez Marin, president of the Chamber of Deputies. "What happens if next time they need to introduce trained assassins or nuclear weapons?"

Hillary's dilemma is this: If this scandal blows out into the open worse than it already has and moves into the "under oath" phase -- and it certainly has every chance of doing so -- does she really want to sink with Obama's S.S. Gunwalker? Or does she seize the moment, slug Obama from behind, jump ship and run for president next year?

Much rests on her calculation of self interest.
