Since when did the ACLU become a staunch defender of the Second Amendment?

(AP) — A federal lawsuit filed in Sioux Falls alleges that the state’s concealed weapons law is discriminatory because it requires the permit holder to be a United States citizen.

The American Civil Liberties Union filed the lawsuit on behalf of Wayne S. Smith, a Minnehaha County resident who has lived in the U.S. for 30 years after emigrating from the United Kingdom.

The lawsuit says he was denied a concealed weapon permit last July solely because he’s not a U.S. citizen.
