More than two dozen district attorneys from across the U.S., as well as two sovereign countries in the Caribbean and 14 U.S. state attorneys, are urging a U.S. federal court to allow the Mexican government to proceed with a lawsuit against U.S. gun manufacturers that the country says are liable for crimes committed with their weapons in Mexico.

The lawsuit filed in Massachusetts last August argues that U.S. gun manufacturers violate highly restrictive Mexican gun laws by actively facilitating the unlawful trafficking of vast quantities of their guns to Mexican criminal groups.
