Most Drug Cartel guns come from the United Statess?

Well, not exactly.

"Nearly 13,000 guns have been lost or stolen from Mexico’s public security agencies over the last ten years, according to a recent report, a telling reminder that the country's black market weapons don't just come from north of the border.

The majority of the 12,878 weapons that went missing or were stolen during that period disappeared in Mexico City, Mexico State, Chihuahua, Guerrero and Jalisco, according to documents from Mexico’s National Institute of Transparency, Access to Information and Protection of Personal Data (IFAI) accessed by Milenio.

In 2009, 800 guns were lost or stolen from local police stations in Mexico City -- 637 handguns and 163 long arms. That was also the year that the most guns vanished nationwide. "

That is enough weapons to arm an Entire Army Division. A Division is between 10,000 and 20,000 personnel. So just under 13,000 firearms is enough to arm a Combat division. And ALL of them came the Mexico Government in one way or another.

So if someone tries to tell you that the Cartels get their guns from the US, they are either intentionally lying or deliberately self deluded and extremely naive.
