Dis-organized citizens with firearms….doing what now? "Arresting" an elected representative or something?
Maybe just showing up armed and peacefully protest? Escort a school board at gunpoint to their cars in the parking lot and telling them "you come back here you die"? Just spitballin here. Oh, what do you tell the State Police or NG when they roll up and have you call covered?
I have a feeling you don't know wtf you're talking a bout because guess what? When it comes to armed conflict, that's a fucking commitment. regular people with guns is basically "regular people". It takes serious organization, training and communications/command structure to actually "stand up".
Civil Disobedience is the Only Way
