The constitutionality of the District of Columbia's authoritarian ban on the private ownership of firearms is being questioned in the courts. The effectiveness of the ban is finally being questioned in mainstream media outlets. In an outstanding article, the Associated Press notes: "Since the ban was passed, more than 8,400 people have been murdered in the district, many killed by handguns. Nearly 80 percent of the 181 murders in 2007 were committed with guns." How? Guns are illegal in Washington, DC.

Must be those rich, white Roman oppressors.

Maybe it has something to do with the fact that Virginia, Maryland and the 48 other states DON'T have gun bans. Its not like they have border checks at the D.C. line.

Yours is a specious argument. A better comparison would be with the UK, although even there its membership in the EU means they have looser border controls than we do.
