Academy city is kind of different lol... They do human experiment on a normal basis. Even when Misaka Mikoto discovered her clones. AC simply ignored her and let her be.

I can't imagine an empire growing in this wonderful but filthy metropolis without being assaulted by Groups like ITEM or something similar. Unless Anderson has some connections like being good friends with one of the Directors of course. Or maybe if his is a small group, but as expansive as conquering whole companies? A bit improbable don't you think? XD
