The US Supreme Court's recent ruling has rendered Mexico's lawsuit against American gun manufacturers inoperative. The suit sought accountability from firms like Smith & Wesson, blaming them for the influx of illegal firearms that contribute to rampant violence linked to drug cartels. Upholding the 2005 Protection of Lawful Commerce in Arms Act (PLCAA), the court affirmed that manufacturers cannot be held liable for the actions of users. During hearings earlier this year, the justices expressed skepticism about Mexico's claims, highlighting doubts about the legal foundation of the case. This landmark decision marks a significant step in the ongoing debate over gun control and international arms trade regulations.
