Four years ago in his book suggesting six amendments to the Constitution, retired Justice John Paul Stevens urged restricting the Second Amendment right to keep and bear arms to service in a militia. Now, in the wake of the Parkland high school shootings and nationwide student demonstrations against gun violence, Stevens is calling for repeal.

The student-led demonstrations on March 24 revealed broad public support for legislation to minimize the risk of mass shootings, Stevens wrote in an opinion column in The New York Times on Tuesday.
