The "Triple-Decker Hoax" of the Second Amendment

Gun enthusiasts look over Charter Arms pistols at the NRA Annual Meetings & Exhibits on May 21, 2016 in Louisville, Kentucky.

The Orlando shootings have revived the intractable debate about guns in America, with Democratic lawmakers pushing legislation that expands background checks and prohibits people on FBI terror watchlists from purchasing firearms.

Bob talks with Slate's Dahlia Lithwick about how the NRA and other interest groups essentially re-framed the meaning of the Second Amendment, cementing the notion that it protects individual gun ownership both in the public mind and in the landmark 2008 Supreme Court case, District of Columbia v. Heller.
