The outstate peeps want to make sure that the citizens of ChiTown behave when they are outside the fence. (both meanings)
I’m not really sure why this is at all shocking. You’re talking about Chicago, a city which has done everything in its power to prevent gun ownership, and even though that was finally broken, a legal gun owning community isn’t going to magically spawn overnight. There are no gun shops in the city from what I understand, and certainly no gun ranges. It rather requires there to be people with guns before you can get people interested in carrying said guns legally.
