This is an interesting topic. Does a B-52 count as arms under the 2A or is it something else? Is an ICBM "arms" in the common sense of the word. Again, it is clear from contemporary writings that the intent was to secure the natural right of the citizens to be armed with individual use/deployed contemporary weapons.
While one person can climb into a fully armed F-15 carrying a nuclear payload and fly that aircraft by themselves to a certain target and launch the nuclear weapon on target, and then destroy numerous other targets outside of the blast radius with the remaining conventional weapons, and while it is only one guy with a big ass fighter aircraft strapped to his back, I just don't think that is the intent or the spirit of the 2nd Amendment. Are we going to argue that any fighter/bomber aircraft that can be operated by a sole pilot is not a crew-served/deployed asset and therefore falls under the 2nd Amendment? So a B-52 can be restricted but we each have a constitutional right to own and operate a fully armed F-16 if we can afford it?
If not, where is that line drawn. Certain high yield explosives? Nuclear devices? RPGs?
Generally I am not worried about fellow law-abiding American citizens owning/possessing such weapons.
The problem is that people, even law-abiding people, are generally stupid. I keep thinking about that guy, I think it was in PA, who had his BAR stolen from his apartment. He was keeping it locked up in a cabinet that I doubt was a tough as what I keep my tools in. So now we have a fully automatic .30 cal machine gun in the hands of criminals because that dumbass stuck it in a cabinet my mother could open with a pry bar and then went out and bragged about owning it. This tool spent $20k (IIRC) on the rifle but not $1k on a decent safe. That is what worries me. I'm not worried about Imperialism, Tarzan or Openryan for example, having an RPG in their gun safe. (Actually I would love to see the video of it being deployed for self-defense - "Freeze or I'll blow up half my house!" Laff), I'm worried about some dill-hole having it in their weakly locked garage next to bulk container of motor oil.
