It's kind of hard to imagine and although I haven't been to those two places, I have been to some dangerous areas.
There's one that goes like this:
You move to country x, you're an internet baller (sweet!) so you open a bank account and have your monies paid in there so that you don't pay tax back at home. Except the bank staff get paid off to give away the details of the top ballers (you) to the mafia/cartel/crims. Good luck when they come and suggest you make a donation to their finger protection fund and you don't like the idea.
But then there are loads of smaller ones, which do get you down after a while.
In my personal experience:
Taxi kidnappings - you get in a 'taxi' (good luck telling the difference), they drive you to a backroad and 2 guys get in with guns. Express kidnapping at an ATM. Happened to an acquaintance of mine last month (and he was a local man).
Shopping center and bank shootouts. Surprisingly regular you just don't realize it till you actually live in the place.
A friend of mine had this happen, he was kinda silly though: Girls who take you to a club with a group of friends. You have a few drinks. Oh wait - you want to leave now? The bill's $2,500. Or a punch to the face. This happened in Eastern Europe, the rest in SA.
To be honest, it's only since I've lived abroad that I've realized how amazingly safe my country is. And how fucking crazy these places are. Even in the richest areas (which is where I stay, what the fuck I'm an internet baller amirite?) the water gets cut off, you get fucked up on some weird food and then when you wake up in the middle of the night with a fever stumbling to the tap you're like, oh shit, that's right, the water from the tap has SALMONELLA
hahaha, I'm not this jaded in real life, really
