MEXICO CITY, Mexico (AP) — The Mexican Government sued United States gun manufacturers and distributors yesterday in US federal court, arguing that their negligent and illegal commercial practices have unleashed tremendous bloodshed in Mexico.

The unusual lawsuit was filed in US federal court in Boston. Among those being sued are some of the biggest names in guns, including: Smith & Wesson Brands, Inc; Barrett Firearms Manufacturing Inc; Beretta USA Corp; Colt’s Manufacturing Company LLC, and Glock Inc. Another defendant is Interstate Arms, a Boston-area wholesaler that sells guns from all but one of the named manufacturers to dealers around the US.

The manufacturers did not immediately respond to requests for comment.

The Mexican Government argues that the companies know that their practices contribute to the trafficking of guns to Mexico and facilitate it. Mexico wants compensation for the havoc the guns have wrought in its country.

The Mexican Government “brings this action to put an end to the massive damage that the defendants cause by actively facilitating the unlawful trafficking of their guns to drug cartels and other criminals in Mexico”, the lawsuit said.

The Government estimates that 70 per cent of the weapons trafficked to Mexico come from the US, according to the Foreign Affairs Ministry. And that in 2019 alone, at least 17,000 homicides were linked to trafficked weapons.

The National Shooting Sports Foundation, the US firearm industry’s trade association, said in a statement that it rejected Mexico’s allegations of negligence.

“These allegations are baseless. The Mexican Government is responsible for the rampant crime and corruption within their own borders,” said Lawrence G Keane, the group’s senior vice-president and general counsel. The Mexican Government is responsible for enforcing its laws, he said.

The group also took issue with Mexico’s figures for the number of guns recovered at crime scenes and traced back to the US. It said that traces were attempted on only a fraction of the recovered guns and only on the ones carrying a serial number, making them more likely to have originated in the US.

Alejandro Celorio, legal advisor for the ministry, told reporters that that the damage caused by the trafficked guns would be equal to 1.7 per cent to two per cent of Mexico’s gross domestic product (GDP). The Government will seek at least $10 billion in compensation, he said. Mexico’s GDP last year was more than $1.2 trillion.

“We don’t do it to pressure the United States,” Celorio said. “We do it so there aren’t deaths in Mexico.”

Ebrard said the lawsuit was another piece of the Government’s efforts against guns. “The priority is that we reduce homicides,” he said. “We aren’t looking to change American laws.”

Mexico did not seek the advice of the US Government on the matter, but advised the US Embassy before filing the lawsuit.

Steve Shadowen, the lead attorney representing Mexico, said that in the early 2000s about 30 US cities brought similar litigation against gun manufacturers, arguing that they should be responsible for increased police, hospitalisation and other costs associated with gun violence.

As some cities started winning, gun manufacturers went to Congress and got an immunity statute for the manufacturers. Shadowen said he believes that immunity doesn’t apply when the injury occurs outside the United States.

“The merits of the case are strongly in our favour and then we have to get around this immunity statute which we think we’re going to win,” he said. “That statute just simply doesn’t apply. It only applies when you’re in the United States.”

He said he believes it is the first time a foreign government has sued the gun manufacturers.

Adam Winkler, a law professor at the University of California, Los Angeles and expert on gun policy, called Mexico’s effort a “long shot”.

“It is a bold and innovative lawsuit,” he said. “We haven’t seen anything like this before. The gun manufacturers have enjoyed broad immunity from lawsuits for now two decades.”

He said he had not seen arguments that the Protection of Lawful Commerce in Arms Act applies only to damages in the United States.

The sale of firearms is severely restricted in Mexico and controlled by the DefenCe Department. But thousands of guns are smuggled into Mexico by the country’s powerful drug cartels.
