The Supreme Court has heard arguments about the meaning of the Second Amendment, and the constitutionality of a District of Columbia law that bans handguns. The justices seemed to be aware of the historical significance of their deliberations, which could provide the first definition of the meaning of the Second Amendment in its 216 years of existence. Justice Anthony Kennedy said early in the proceedings that the Second Amendment gives "a general right to bear arms." But what that means to the D.C. law is less clear. During the arguments, Justice Stephen Breyer asked if it's unreasonable for a city with a high crime rate "to say no to handguns." Chief Justice John Roberts took the oppposite side, asking at one point: "What is reasonable about a ban on possession" of handguns? The 32-year-old handgun ban, perhaps the strictest in the country, was overturned by a lower court. This is the first time the high court has looked at the Second Amendment since the 1930s.
