It gets wacky in dramatically less developed places with a weak rule of law
I agree with this. Everything gets “ wackier” without a rule of law.
But what is traceable and clear, are the amounts of US sourced guns recovered abroad in Central America and the Caribbean and submitted to be traced to ATF.
Weapons do not cease to be an issue if they can be trafficked to add to death rates and crime abroad.
“From 2014 to 2016, 50,133 guns that originated in the United States were recovered as part of criminal investigations in these 15 North American, Central American, and Caribbean countries,[30]
many of which receive more crime guns with origins in the United States than some U.S. states. For example, from 2014 to 2016, more than 33,000 U.S.-sourced guns were recovered in criminal investigations in Mexico. That exceeds the number of crime guns recovered and traced to a U.S. source in every U.S. state during the same period—except for California, Florida, and Texas.[31]
Similarly, from 2014 to 2016, both Canada and El Salvador recovered more U.S.-sourced crime guns than 20 U.S. states.

Here are the ATF reports by country to click

Though slightly off topic, since the article in the OP is positive news and a creative approach with good results.
Unfortunately, guns that disappear from an area, appear somehow somewhere else…
