the courts have determined that
no rights are absolute!!!
the 2a doesn't protect or grant anyone the right to use any type of gun anywhere, anyhow on anyone or anything they like. It's just common sense that felons and lunatics shouldn't have the right to own a gun. People also have the right not to have guns on their private property. Ergo, rights are limited. Not sure but i think all of the amendments have limits on individual rights to some degree.
"...in countries which have bills of rights there is a basic statement of freedoms subject to permitted abridgment of such freedoms. Freedoms are restricted in the public interest on grounds of national security, to preserve public order, to protect public health, to maintain moral standards, to secure due recognition and respect for the rights and freedoms of others or to meet the just requirements of the general welfare of a democratic society. The united states supreme court has over the years qualified the rights in the constitution. Any statement of rights is not absolute and must of necessity be subject to limitations on the above lines. The right of free speech and expression does not extend to sedition, slander, defamation and obscenity. The principle of equality before the law cannot deny a legislature the power to classify persons for legislative purposes and to legislate affecting them, provided that the classification is not arbitrary and is based on a real and substantial distinction bearing a reasonable and just relation to the objects sought to be achieved. Thus the legislature could enact legislation regulating the activities of money lenders. This would amount to a singling out of money lenders and would be prima facie in conflict with the principle of equality before the law. But provided the classification is reasonable and there is a legitimate object to be achieved the legislation would nonetheless be valid. The above are instances of legitimate restrictions of rights. They are intended to illustrate that
no right available to an individual or group is or can be absolute. This seems obvious but is often not appreciated."
human rights are not absolute
the "obvious" is something the founders probably didn't think needed enumerating in the bor. But like the invention of the cotton gin...if only they had known about the nra, gang violence and mass shootings they might have been more specific.
