Mexican authorities have long complained about American guns flooding their country, and now they may have proof. U.S. officials arrested 17 people in Arizona Tuesday, saying they were part of a smuggling ring that made legal purchases of about 700 guns—including AK-47s and semi-automatic handguns—and then turned around and sold the weapons to the Sinaloa cartel, a leading Mexican drug gang, illegally. Overall, charges were made against 34 Arizonans. Authorities say all of the suspects are either American citizens or legal residents. "Drug cartels go shopping for their war weapons here in Arizona," said U.S. Attorney Dennis Burke.
