Prison armory/dead guards (not like the dead guards themselves, the stuff they have on them, that'd just be weird), that shit sells. Also I'm thinking about another character I'd introduce through this, not sure if I'll do it.
Besides, if you hear a prison break's happened, big enough for half the damn League to be deployed, you're running for the hills. Plenty of stores, ripe for the picking, and the cops'll be too focused on the quadruple life-sentence serving guys running loose in Chicago to worry about a borderline-malnourished chick knocking over a Radio Shack.
