The trade in guns and drugs on the Mexico-US border

 It's well known that a lot of illegal drugs enter the U.S. over the border with Mexico.  Less well known in the U.S. is that a lot of guns cross illegally into Mexico over that border, destined for Mexican drug cartels.  

Here's a story from the Guardian:
How Texas’s gun laws allow Mexican cartels to arm themselves to the teeth by Sam Garcia.

"Despite Mexico’s well-documented high levels of violence, legally purchasing guns there is actually quite difficult. The nation of nearly 130 million people has a single store that can legally sell guns.

...

"Mexican foreign affairs ministry legal adviser Alejandro Celorio Alcántara estimates that half a million guns annually are purchased legally in the US and then brought into Mexico illegally. About 70% of guns seized in Mexico from 2014 to 2018 and submitted for tracing had originally come from the US, according to officials with the American bureau of alcohol, tobacco, firearms and explosives (ATF).

Dribs and Drabs: The Mechanics of Small Arms Trafficking from the United States

"Robust arms export licensing regimes are necessary but not sufficient for stopping small arms trafficking. Many of the traffickers studied did not apply for arms export licences or attempt to exploit licensing exemptions; they simply bypassed the licensing system entirely. At the same time, recent examples of attempted and successful diversion of authorized small arms exports highlight the continued need for rigorous licensing and post-shipment end-use monitoring.

"Arms trafficking from the United States goes well beyond gun-running to Mexico. Traffickers in the 159 cases studied shipped weapons, parts, ammunition, and accessories to at least 46 countries and foreign territories on six continents. Intended recipients of these items range from Honduran farm workers to a Finnish motorcycle gang 

"The illicit trade in parts and accessories for small arms is more significant than commonly assumed. Networks that traffic in firearms parts are among the most prolific and geographically expansive of the smuggling operations studied"
