Weapons Traffic: As Mexico drug violence runs rampant, U.S. guns tied to crime south of border

As Mexico drug violence runs rampant, U.S. guns tied to crime south of border: "As an unprecedented number of American guns flows to the murderous drug cartels across the border, the identities of U.S. dealers that sell guns seized at Mexican crime scenes remain confidential under a law passed by Congress in 2003.

A year-long investigation by The Washington Post has cracked that secrecy and uncovered the names of the top 12 U.S. dealers of guns traced to Mexico in the past two years. Eight of the top 12 dealers are in Texas, three are in Arizona, and one is in California." Dec. 12, 2010, Washington Post
