That's not how Gallardo got arrested at all. They made it look like the cartel turned on Felix because he was too greedy, when in reality they apparently didn't turn on him at all but instead he kept running everything from prison and still remained the boss after his arrest? See wiki

I don't mind them taking liberties or making up characters (for example McNairy's character didn't exist at all in any capacity), but it seems strange to change such major details about the main, real-life characters stories. There was something else along the same lines too that bothered me, but I already forgot what it was.

Edit: Bunch of unmatching stuff about El Chapo too. Am I being too nitty or is it really weird they chose to fabricate the whole main storyline of the show instead of using the real one which IMO would have been more interesting as well?

By the way, this is what actually happened with Guadalupe (from wiki):

This one I can understand a bit better, but given all the violence in the show, why not use it? They also made it look like it was Felix who ordered that, when apparently he had nothing to do with it

what are the chances Amado is still alive?

Been reading about it. Apparently the doctors who did the surgery were killed shortly thereafter, but it could have been retaliation vs. covering it up. Couple people confirmed the body was his, but there were a few stories of people saying he was still alive, even a person claiming he was flipped by the DEA.
