The U.S. Supreme Court unanimously rejected Mexico’s lawsuit against American gun manufacturers, ruling that the Protection of Lawful Commerce in Arms Act shields them from liability. Mexico accused companies like Smith & Wesson and Glock of enabling gun trafficking to cartels. However, the court found no evidence the firms directly aided illegal sales. Filed in 2021, the lawsuit blamed U.S. guns for Mexico's violence and high homicide rates. The court said legal weapons, even if misused, don’t imply manufacturer responsibility. Gun rights advocates hailed the decision as a victory, emphasizing responsible ownership over blaming manufacturers for criminal misuse abroad.
