Your proposal assumes most of the MAGA wacko nutjobs aren't armed up to handle bloated FBI and poorly trained local law enforcement.
I'm lower-middle class and barely own under 1k rounds of ammo for various guns thanks to blue laws making it cost-prohibive, and that shit is expensive af in states with sane gun laws.
The rural MAGA retards spent their paychecks on ammo in their shithole red states and can buy an essential entire arms room for way cheaper. Good luck to the rural law enforcement guys with high school educations fighting brainwashed retired war veterans that have gone through several mandatory post-college quality military schools.
