Well, let's just lay down and die, then. There's nothing we could possibly do.
My point is this, the legal stuff such as rifles and handguns is pretty useless against tanks and fighter planes. For the Second Amendment to actually work in keeping the people free from dictatorship then such things as antitank missiles or privately own and armed fighter planes should be allowed.
The Second Amendment said the right to bear arms shall not be infringed. Arms was not just firearms but cannon and sword and other weapons of war in 1776. Yet we the people have restricted the Second Amendment to only firearms and has taken such weapons as working antitank missiles or armed fighter jets from the public.
As such any rebellion by groups armed only with legal firearms can be crushed easily by the government. Only illegal weapons such as anti aircraft missiles can even give the rebels a chance.
