Mexico has restrictive laws regarding gun possession. There are only two stores in the entire country, DCAM near the capital, and OTCA, in Apodaca, Nuevo León. It also takes months of paperwork to have a chance at purchasing one legally.
If I was living in the US, I'd definitely stock up on guns and ammo at this point. Not that it'll help, when the fascists come for you, but at least I wouldn't go down without a fight.
This is the one reason I’m happy Biden was in office. It gave everyone four more years to prepare. Marginalized communities were some of the heaviest buyers during that time. Small arms have been used to inflict losses on fascists since fascists became a thing. Disarmed groups are substantially more in danger than armed groups.
