Hopefully, if history has taught us anything, it's that military superiority doesn't mean squat against an indigenous force willing to engage in guerrilla warfare in order to ensure their survival. All the same, I wouldn't mind having the same equipment though.
And with that said, I don't think crazy people and criminal should be allowed to own weapons. 2nd Amendment or no.
How we protect our rights and ensure our safety would probably be a productive conversation worth having.
