” . . . The right of the People to keep and bear arms shall not be infringed.”
Since the Supreme Court affirmed (in the District of Columbia v. Heller) that the Second Amendment applies to individuals, there’s not much room in that statement for a need to justify *which* arms to keep and bear.
In fact, you have the right to your guns because of the inalienable right to life, not in spite of it. The right to defend your life is a corollary of the inalienable right to life, which is actually the right not to be killed.
“But,” someone asked me last week during an online discussion, “what about owning an AK-47, an armored tank, or even nuclear weapons?”
A gun or a tank in my neighbor’s yard is not a threat to my life, liberty or property until it’s pointed at me, by an imminent threat or in actuality.
On the other hand, nuclear materials are a real threat to the possessor and those around him, even without a trigger. Because they give off dangerous radiation and decompose (making them even more dangerous) it’s not unreasonable to regulate who may and may not possess nuclear materials, how they’ll be manufactured, stored and transported. Governments may ethically limit their possession because, like biological or chemical weapons, they’re hard to contain, much less accurately aim. They all are able to threaten people nearby, downwind and may even harm future generations.
Inalienable rights aren’t decided by government, much less personal opinion. They are negative and necessarily hierarchical. You may not enjoy a liberty that endangers the life of another, and the government can’t limit rights without prior evidence of a clear infringement of another’s rights.
