So Colombia, Mexico, Brazil and El Salvador are the main centers for organized crime in Latin America?
I thought of ELN as a paramilitary group as well, but Colombia has always had a major crossover between paramilitary groups and drug trafficking networks.

I would've thought that the drug trafficking networks in for instance Dominican Republic and Puerto Rico are more organized than those in El Salvador, but maybe they didn't count in the Caribbean.

Suriname tends to be glossed over, but there are major drug trafficking cells at work there. Lots of former Jungle Commando guerrillas are involved as well; plenty of them invested in real estate, sports clubs, etc... in Marowijne.
