This brief piece at wola’s website is for anyone who seems to think that you can fight opioids by aiding Central America, that a border wall can stop drugs, that gangs like MS-13 ship drugs to the United States, or that Mexico stops a lot of northbound cocaine.
I leaned heavily on my database to cite facts that aren’t, but should be, well known about how the drug trade works in the Mexico-Central America “transit zone.”
