Supreme Court (AP) What does the second amendment's right to “bear arms” provision really mean?
That question is at heart of arguments before the Supreme Court today.
The court is taking up a dispute over Washington, D.C.'s handgun ban.
At issue is whether the constitution protects an individual's right to own guns or if that right is tied to service in a state militia.
Even if the high court determines individuals have the right to own guns, the justices will still have to decide whether the 32-year handgun ban in the district can stand.
The case is among the most closely watched of the term because the current nine justices and their predecessors have given no definitive answer on gun rights.
