"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. "

In spite of extensive recent discussion and much legislative action with respect to regulation of the purchase, possession, and transportation of firearms, as well as proposals to substantially curtail ownership of firearms, there is no definitive resolution by the courts of just what right the Second Amendment protects. The opposing theories, perhaps oversimplified, are an ''individual rights'' thesis whereby individuals are protected in ownership, possession, and transportation, and a ''states' rights'' thesis whereby it is said the purpose of the clause is to protect the States in their authority to maintain formal, organized militia units.1 Whatever the Amendment may mean, it is a bar only to federal action, not extending to state2 or private3 restraints.

The Supreme Court has given effect to the dependent clause of the Amendment in the only case in which it has tested a congressional enactment against the constitutional prohibition, seeming to affirm individual protection but only in the context of the maintenance of a militia or other such public force.
