One thing that would be interesting to see is how criminals operate in Legion territory. We’re led to believe that the Legion is so brutal that crime and corruption simply don’t exist, but from what we know about (fallout’s depiction of) human nature, this obviously isn’t the case. In Legion territory you wouldn’t find the drugged out psycho raider gangs that exist elsewhere in the wastes, and crime syndicates wouldn’t operate so openly like Gizmo, Decker, and Merk seem to.
The only “raiders” would be well-trained, well-armed groups that the Legion is unable to take on without significant losses. These groups would only strike sporadically, as if they drew too much attention to themselves then the Legion would just go all out and eradicate them. These gangs would be more like outlaw bank robbers (or rather, train robbers, as they’d be mostly raiding caravans) than your average wasteland punk raider. And as far as criminal enterprise, drug and alcohol smuggling would surely be profitable, but the consequences of doing so in Legion territory is so severe that these smugglers would be much more professional and stealth-oriented than their counterparts in a place like NCR.
The harshness of Legion rule would do much to reduce crime (in theory), but it could ironically lead to the development of highly trained crime syndicates and gangs.
