there is estimated 100million gun owners in America......lets say it is half that versus the 500,000 combat effective units in the military........sure the government has tanks, and gunships, and jets, and drones. But those are unbelievably expensive, they cant mass produce them like they did in WWII.....and they are expensive to use, to upkeep, to get ammo for ect ect. also, most of it is over seas anyway.
so all that taken into account, 500,000 vs 50,000,000 is hands down in the favor of the gun owners....
now would a lot of people die? absolutely! millions of people would die but that isn't the point.
Also we couldn't stop the Taliban with all our High Tech weaponry...
So the notion that the people would lose is highly unlikely statistically speaking
with all due respect
