“where there is a Mexican. There is Mexico.”
Anyone who lives in a town/city they have invaded can attest to that.
We have a 5 square mile area here that looks just like Mexico, and is just as dangerous to go into. 75% of our city’s resources (police,fire) is there at any given time of the day or night. The other areas of town get put on a ‘priority’ list.
You just described about 100 town/cities in the US - where do you live?
