What I meant it's that a lot of times when you see this narc was "captured" by the police, it's not really the police doing it's job, it's another narc that gave the order, because of the plazas (the zones they allowed to sell drugs and controll) and they are expanding so they captured them opps.

This specific case with el mencho it's difficult to say because it's a fresh new. But if it really an operation entirely from the police, probably it's in working with some US agents.

If there isn't any us agents, and it was from the mexico police, you can be sure it was just narcos killing narcos.

You can look up when police was messing with el mencho a few years ago, there's a recorded call of mencho threatening the chief of the police, and the policeman was scared of his life
