From Reason:

When the American Civil Liberties Union of New Jersey announced its lawsuit on behalf of two public high school students who were suspended because they posted pictures of themselves at a gun range on Snapchat, the first reply on Twitter congratulated the organization for “defending all of the civil liberties.” But while the ACLU is commendably willing to defend the First Amendment rights of gun owners and Second Amendment advocates, the national organization still takes the position that, contrary to what the Supreme Court has said, the Constitution does not guarantee an individual right to armed self-defense.
