Except the shitty restaurant has AK-47s pointing at you and has locked the doors.
What might be obvious to everyone else is that the endlessly more efficient thing for an organised group with guns (cartel) to do would be to get a monopoly.
And by the way you know you can already live in countries where cartels control things- Mexico or Somalia. Remind us where you live again?
But if you can provide a single historical or current example of where the general population refers to their cartels as ‘honest security firms’ I’m all ears.
