Fair enough, is escaping violence why the come here? If it is, why not do what some have done from St. Louis and other violent US cities and just move to smaller towns?
They aren’t escaping random big city violence. You are doing just like the Australians who would tell me that the US could simply buy back guns and solve the gun problem since that worked there. The issues they are dealing with are completely different than the very limited perspective you are displaying.
