The right to bear arms is famously and specifically referenced in the Second Amendment to the U.S. Constitution. Alas, for advocates of the right, the language of the amendment gets tangled up in the regulating of militias and the interpretation of commas.

The 10th Amendment declares, "The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."
