We may indeed have that right, but that cannot be inferred from a fair reading of the second amendment.
It actually can. Gun control advocates simply like to ignore the second part of the amendment, and pretend it is only concerned with the militia.
“A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed”.
“A well regulated militia, being necessary to the security of a free state” is a related but separate statement to “the right of the people to keep and bear arms shall not be infringed”.
At the start of the American Revolution the British Government sought to disband the various state militias in order to establish peace and enforce the will of Parliament with the standing army. With this in mind, the general concern after the revolution was that a federal government with the power of a standing army would wish to defund, neuter, and break up any state militias in order to potentially use the standing army to enforce the will of the federal government. They therefore codified that the militia could not be broken up.
The “militia”, being the armed, able bodied, and trained subset of the population, naturally had to be drawn from the population at large. It was therefore necessary for the entire population to be generally armed.
“The people” referes to all members of the community, and in the context of the constitution always refers to an individual right. If the intent was to only allow the militia to keep and bear arms, the amendment would have read “the right of the militia to keep and bear arms shall not be infringed”.
Lastly, “bear arms” simply means to have weapons and is not tied to a military function.
Essentially, the amendment identifies the pressing governmental purpose of having a functioning, trained militia as an example to be derived from the inherent right to self defense through weapon ownership. The scope of the “right to bear arms” is not limited by “militia”.
Or, if you wish to hear from the Supreme Court:
“The Second Amendment protects an individual right to possess a firearm unconnected with the service in a militia, and to use that arm for traditionally lawful purposes, such as self defense within the home”.
And just for Jig:
“We know of no other enumerated constitutional right whose core protection has been subjected to a freestanding ‘interest-balancing’ approach”.
