Washington Post, 5/21/2010
MEXICAN PRESIDENT Felipe Calderón has shown courage in leading his government to take on the violent drug gangs that have claimed thousands of Mexican lives. On Thursday, he displayed a different kind of fortitude: standing before a joint meeting of Congress and asking for a revival of the U.S. assault weapons ban. The Obama administration, which has been largely absent in the fight against the illegal gun trade, should have such backbone.
Mr. Calderón, who has been in Washington for a state visit, made a powerful case. Over the past three years, Mexican authorities have seized some 75,000 weapons used in crimes; more than 80 percent of those they were able to trace came from the United States. Mr. Calderón argued that the surge in violent, cartel-related crimes coincided with the 2004 repeal of the U.S. assault weapons ban.
