At the outset of the effort that led to our constitution, most of the cannon were either owned by private citizens, were common property of the various militias or were stolen from the crown. Hell yes, the 2nd Amendment means cannon, tanks, bombers, the whole works.
Thats right. ‘Arms’ means any weapons of war. No restrictions if you can afford it and maintain it. And ‘well regulated’ means you know how to use them.
If it’s good enough for the federale gov then it’s good enough for the citizens - the founding fathers warned against a standing army, and forbid the feds for infringing on arms. If it can be used in war for offense or defense, it’s an arm.
Don’t let the leftard/commies derail the conversation. If it’s an arm, they are forbidden from infringing on our having or using said arms.
