Although the Heller decision adopted the broader, individual-rights interpretation of the Second Amendment, the Court made it clear that the right to possess a gun continues to have a number of significant qualifications or restrictions. The Court indicated that the Second Amendment continues to allow for limits on guns like the following:
Not allowing everyone to possess a gun. The right can be withheld from felons and the mentally ill, for example.
Not allowing guns to be carried everywhere. Laws forbidding people from carrying firearms in "sensitive" places, such as schools and government buildings, remain valid.
Certain restrictions on the sale of guns. Laws imposing conditions and qualifications on the commercial sale of firearms continue to be allowed.
Banning certain types of guns. The Second Amendment does not protect guns that are not typically possessed by law-abiding citizens for lawful purposes, such as short-barreled shotguns. (The Court endorsed the "the historical tradition of prohibiting the carrying of 'dangerous and unusual weapons.'")
Outlawing concealed weapons. Laws prohibiting concealed weapons probably remain valid.
