Doubt it.
Government knows already it cannot control what, 15 million illegal immigrants?
If the SHTF, the government will focus on certain things:
The government itself
The large urban centers
The transportation corridors
The power generation and infrastructure facilities
The food movement and distribution networks
Government ain’t gonna give a squat about Joe-Bob sitting on his ten acres 100 miles from Podunk. Besides, I would bet that if anything big happens, government would kinda take it as granted that 75% of the people wouldn’t give a rats rear about any laws that get passed.
The govt can control the illegals anytime they want. They don’t want too. But they could. It would not be pretty, but they could.
That would quickly change if Joe Bob and his clan began forming opposition political parties and organized resistance.
new meaning to “fly over country”.
