U.S. Is Arms Bazaar for Mexican Cartels

"Drug gangs seek out guns in the United States because the gun-control laws are far tougher in Mexico. Mexican civilians must get approval from the military to buy guns and they cannot own large-caliber rifles or high-powered pistols, which are considered military weapons."

"The gun laws in the United States allow the sale of multiple military-style rifles to American citizens without reporting the sales to the government, and the Mexicans search relatively few cars and trucks going south across their border."

"What is more, the sheer volume of licensed dealers — more than 6,600 along the border alone, many of them operating out of their houses — makes policing them a tall order. Currently the A.T.F. has about 200 agents assigned to the task. "

"The Mexican government began to clamp down on drug cartels in late 2006, unleashing a war that daily deposits dozens of bodies — often gruesomely tortured — on Mexico’s streets. President Felipe Calderón has characterized the stream of smuggled weapons as one of the most significant threats to security in his country. The Mexican authorities say they seized 20,000 weapons from drug gangs in 2008, the majority bought in the United States. "

"In 2007, the firearms agency traced 2,400 weapons seized in Mexico back to dealers in the United States, and 1,800 of those came from dealers operating in the four states along the border, with Texas first, followed by California, Arizona and New Mexico."
