It raises the viability of the 2nd Amendment giving allowance to the average citizen(s) of maintaining parity with the country's armed forces in regards to "bearing arms" in order to thwart a "government gone wild", so to speak.
I personally don't see anything good coming from separate "thrown together" citizens' militias or individuals having weapons such as 50 caliber machine guns, cluster bombs, fully automatic weapons, etc., just in case the government goes butt crazy. We already have mass shootings occurring on an almost regular basis. Regardless of who has the weapons, it just takes one disgruntled individual to get their hands on one and there goes the neighborhood.
Unless there's going to be a separate citizens militia set up in the country that maintains the same kind of screening, training, control, and discipline within its ranks that our country's regular armed forces have, then the 2nd Amendment is moot in this aspect.
Even with every citizen armed with fully automatic rifles, if for some reason or other the government decides to go all tyrannical, its not going to make much of a difference. If things go that far, its because people have the general attitude that if it doesn't affect them, they don't care as long as someone throws them a bone every now and then...
When you get to the root of the problem, its not something that can be rectified by arms and ammunition, but rather spiritual and what we're having psychologically shoved down our throats day in and day out. We're basically doing it to ourselves, not the government. The government's behavior is just a symptom of the problem and not the problem itself.
