Gunmakers Shielded From Mexico Lawsuit, Supreme Court Rules

The US Supreme Court threw out a Mexican government lawsuit that accused gunmakers including Smith & Wesson Brands Inc. and Sturm Ruger & Co. of helping to funnel firearms to the country’s violent drug cartels.

Voting unanimously, the justices said Mexico’s suit was barred under a 2005 US law that gave the gun industry broad protection from legal liability.
