That makes sense only in the middle of the sentence, so Vigilantes are going to be shooting vigilantes. That's gonna be interesting.
While the idea is definitely good, in my honest opinion, it has little place in the state of current affairs in Liberty. To use the D&D alignment system (it is also a roleplay system after all), there is an absolute overflow of chaotic entities while the lawful ones are in minority. I can't help but notice that people seem to think the only balance is needed on the good-evil axis.
