While I understand concealed carry for self-defense, if a first world government, especially that of the US, wants to truly be tyrannical, they will. They have nukes, stealth bombers, drones, and god knows what nowadays.
There are 1.5million active duty military personnel. 80 million civilian gun owners. That is a non-trivial difference in numbers. I doubt a boomer captain would follow an order to nuke Seattle. Regardless of the situation.
Nukes and tanks are useless in a guerrilla war.
