It seems to me that at some point they're just gonna kill each other off. Natural selection and whatnot. There's rather consistently high murder numbers there.
As long as they keep militarized police guarding the parameter of the city, I'd say let em go at it. Keep em contained, but let em go at it.
If we're gonna have militarized police, we may as well use em for something practical.
Maybe there can be a curious glitch in the ebt system that can't be fixed for a few months....hm...let's say we dunno, maybe it was a Russian cyber attack?
That'll solve the problem in a hot minute, no doubt.
