I agree that it won't get to that. but if it did, barring massive police/military mutiny, who do you think is going to win that one? If both sides have guns, I'd say it will likely be the side with more training, experience, body armour, huge ammo stock piles and armoured vehicles. Unless the majority of the police/military mutiny I don't think even the US civilian population with your ridiculous amount of guns could prevail.
