“when does an American citizen get the right to obtain and operate a missile battery”
They don’t.
I don’t think thats what the 2nd Amendment was intended for.
If you want to shoot some people coming across the border, go for it. But expect to spend some time in jail.
“I don’t think thats what the 2nd Amendment was intended for”
Then we disagree fundamentally.
You can be assured that my Patriot ancestors in the Carolinas were not fighting for Monarchy 2.0. The guns they used came from the mantle over the fireplace and were no different from the ones the other guys were using.
As for shooting people coming over the border, you will note that a Patriot missile is a special class of anti-missile missiles, mainly for theater defense. Wouldn’t be particular useful against Sinaloa mafia guys unless they have their own Surface to Surface missiles.
