The Founders never intended to create an unregulated individual right to a gun. Today, millions believe they did. Here’s how it happened.

“A fraud on the American public.” That’s how former Chief Justice Warren Burger described the idea that the Second Amendment gives an unfettered individual right to a gun. When he spoke these words to PBS in 1990, the rock-ribbed conservative appointed by Richard Nixon was expressing the longtime consensus of historians and judges across the political spectrum.

Twenty-five years later, Burger’s view seems as quaint as a powdered wig. Not only is an individual right to a firearm widely accepted, but increasingly states are also passing laws to legalize carrying weapons on streets, in parks, in bars—even in churches.
