What are the specific terms of the ruling?The court essentially said state and local laws banning handguns (which preclude citizens from owning handguns for self-defense in the home) are too strict. The decision flows directly from the court's ruling in the 2008 case, District of Columbia v. Heller, which struck down Washington, D.C.'s blanket ban on handguns. While that case already addressed the meaning of the Second Amendment by affirming the right of citizens to own handguns, it applied only on a federal level. (D.C. is under federal jurisdiction.) This case — by way of the due process clause of the 14th Amendment — extends the same interpretation of the Second Amendment to state and local levels. Taken together, these rulings say that the Constitution bars various levels of government from banning handgun ownership.
Will this ruling affect gun laws where I live?For now, this Supreme Court ruling is only likely to affect gun laws in Chicago and Oak Park, Ill. — there is no immediate effect on any other laws. So if you live in another city that restricts gun possession in some way, that law remains in effect for the moment. Both the National Rifle Association and the Brady Center to Prevent Gun Violence say no other communities currently ban handgun possession in the home, so no other laws are clearly rendered unconstitutional. However, this Supreme Court ruling on the Second Amendment can be used to challenge other gun laws in cities and states. So this case may result in incremental change across the country as gun laws are challenged one by one.
If I live in a city where handgun ownership is restricted, can I buy a handgun now?No, you will still be subject to the restrictions that were already in place. So if you had to get a license to buy a handgun, you will still need to go through that process. Even in Chicago and Oak Park, the cities where the handgun bans were challenged, the restrictions remain in place for now. The high court interpreted the Constitution but left the actual decision regarding the cities' laws to a lower court. It's likely under the Supreme Court's ruling that the lower court will find the laws unconstitutional, and at that time the cities will probably be able to rewrite their laws to comply with the ruling while still enacting some gun restrictions.
Does this mean I can purchase any kind of gun I want?No. The Supreme Court has previously ruled that ownership of many kinds of guns, such as assault weapons, can be banned.
Does this mean felons can purchase guns?No. Just as the Supreme Court has allowed restrictions on the kinds of guns people can own, it has permitted some restrictions on who can own them. The Brady Center notes that the federal Gun Control Act of 1968 explicitly bars felons from buying guns.
How does the ruling affect carrying weapons in public?It doesn't. This ruling affects only handgun ownership, not where you can take that gun. So laws that prohibit guns in public still stand.
