We support them in more ways that people realize. Should it come to the catastrophic point where law-enforcement fails or becomes overwhelmed, the armed citizens are always there. We are the last line of defense in this country, should our brave law-enforcement and military personnel fail.
then the country is fucked
Not really. The only people who are truly fucked are the degenerate lawbreakers. Armed citizens don't have the power to arrest, so consider them more of a threat than law-enforcement officers.
They won't yell at you to "drop the gun", they'll just shoot you in the fuckin' back a couple times and then go home to eat supper with their wives and kids, like nothing ever happened.
The best thing you can hope and pray for is that social order never breaks down in this country. Because if it does, I can guarantee that it will get uglier than your little minds can comprehend.
