Listen, I know Evan told us to only fire warning shots if you see any of those Fanatic assholes rummaging around.
But I'm telling you, if you see one, you put a shot right between their sub-human eyes. We both know they wouldn't afford us the courtesy of a "warning shot".
Besides, as far as I can tell they aren't going anywhere any time soon. The fewer of them around the better our chances are.
