In parts of Central America, I absolutely felt unsafe. Civilian Militias with guns blocking the roadways. Anything of value was guarded by a guy with a shotgun. Things I saw guarded first hand: - Gas Station - Truck with Propane Tanks (Guy was laying in back on top of the tanks) - Banks - Honda Motorcycle dealership - Motels
I was never sure how to feel about the guys guarding our motels with a shotgun. On one hand, it's nice to know there is someone there deterring any weird activity. On the other hand it also means you're in a place where a guy with a shotgun is necessary to protect stuff.
Most places the locals would look at you and have a warm curious smile. In the sketchier areas the smiles were gone. You'd get stares. Stares that said, 'Why would you think it was safe to be here.'
That being said, these sketchy, unsafe areas were not the norm in Central America. Most places I felt completely safe and absolutely welcomed.
Dissolving people in acid was common, having a dedicated mafia graveyards was also common. They had units of assassins that served as hitmen and were connected to the intelligence services. They had access to explosives, sniper rifles and even at some point were able to detonate the bombs remotely (remember this was in the 90s very early after the fall of the Iron Curtain and such devices were really uncommon).
In the El Chapo show, there's a group called "Los Emes" which is basically "Los Zetas"[0] and when I was in Mexico my brother in law told me they were the most dangerous group in Mexico, he certainly was not wrong.
As other comments have shared there's crazy violence in the border alone, a coworkers wife heard gun shots from Texas every day she was near the border for Hurricane relief.
In Puerto Rico where I'm from right now people are killing people in daylight[1], for what reason? Who the heck knows, it could be anything: looked at you wrong, owed drug money, whatever. When a big time drug lord gets arrested what ends up happening is people start killing each other to get to the top. Cops are resigning to work elsewhere in the continental USA due to loss of basic benefits. The former police chief in Puerto Rico doesn't even go outside after night time[2].
Puerto Rico isn't necessarily Latin America, and most people wont see the worse things happening in their lifetime if they don't live in those rough areas, but the cartels are pretty damn awful. I'm sure Netflix / Telemundo (or was it Univision?) wont get every detail right, but plenty of it is pretty darn close.
That all said, I still would go back to Mexico and Puerto Rico. I love both places, I would still be weary whilst in either of those places, but you gotta know where to go really. Drug Cartels are pretty brutal and have massacred civilians.[3]
