A funny thing has happened in the three years since gun-rights activists won their biggest victory at the Supreme Court.

They’ve been on a losing streak in the lower courts.

The activists found the holy grail in 2008 when the Supreme Court’s 5 to 4 decision in District of Columbia v. Heller said the Second Amendment guaranteed an individual right to own a firearm unconnected to military service. The court followed it up with McDonald v. Chicago two years later, holding that the amendment applies not just to gun control laws passed by Congress but to local and state laws as well.

The decisions were seen as a green light to challenge gun restrictions across the country, and the lawsuits have come raining down — more than two a week, according to the anti-gun Brady Center to Prevent Gun Violence.
