While reporting on the ongoing drug war in Mexico, CBS, NBC, and ABC have all cited a dubious statistic that claims that 90% of the guns being used in the violence are from the United States. On Thursday’s CBS Evening News, correspondent Bill Plante reported: "Mexican drug gang violence spilling into the U.S. is the urgent issue of President Obama's visit...A major sore point -- more than 90% of the weapons which could be traced were bought legally in the U.S. and smuggled into Mexico by the cartels."
On Thursday’s NBC Nightly News, White House correspondent Chuck Todd declared: "In a joint press conference following their private meeting, President Obama acknowledged that 90 percent of the guns used by the drug cartels in this war with Mexico come from the United States." On Thursday’s Good Morning America on ABC, co-host Diane Sawyer referenced, and even further embellished, the figure while interviewing Homeland Security Secretary Janet Napolitano: "95 percent of the guns used were out of the United States. What is the U.S. going to do to stop the guns from getting there?"
However, on April 2, Fox News reported that 90% figure to be inaccurate: "The fact is, only 17 percent of guns found at Mexican crime scenes have been traced to the U.S. What's true, an ATF spokeswoman told FOXNews.com, in a clarification of the statistic used by her own agency's assistant director, ‘is that over 90 percent of the traced firearms originate from the U.S.’ But a large percentage of the guns recovered in Mexico do not get sent back to the U.S. for tracing, because it is obvious from their markings that they do not come from the U.S." The network reports failed to explain those details.
