The Supreme Court tossed Mexico's $10-billion lawsuit against U.S. gun makers, but the case forced U.S. officials to acknowledge that thousands of guns are smuggled into Mexico from the United States.

The Supreme Court is tossing out a $10 billion lawsuit Mexico filed against top U.S. firearm manufacturers alleging the companies fuel cartel gun violence.

Mexico claims that U.S. firearms manufacturers know their guns are trafficked into the country and that they intentionally target the Mexican market, including drug cartels.
