I remember reading that Mexico filed a lawsuit against the US gun manufacturers in 2021because of the influx of guns into that country. It was a horrible event that led up to the decision to file the suit. A convoy of cartel thugs apparently drove into a town along the border, with the intention of terrorizing the community for the purpose of taking it over. Just shooting up the streets and anyone who was unfortunate to be caught outside! They killed 15 people. And the weapons that were eventually taken by the authorities had one thing in common, all made in the USA.
Are U.S. Gun-Makers Responsible for Violence in Mexico?.
Shocking that a Texan, probably someone who complained aggressively about migrants coming in, was found responsible for many weapons confiscated in Mexico. But I've read that Texas doesn't make gun show sellers do back ground checks or keep records, so not surprising that some enterprising thug wouldn't be involved.
