Justice Watch: Does stopping the carnage require changing the Supreme Court?

Lisa McElroy, Associate Professor of Law at Philadelphia's Drexel University Earle Mack School of Law, wrote this in a column for The Huffington Post:

[T]he Supreme Court expert in me is talking to the mother in me. And the Supreme Court expert in me knows that the only way to even think about stopping the carnage that the mother in me hates is to appoint Justices to the bench who believe that the Court's current interpretation of the Second Amendment is wrong. Even one new Justice who believed that guns were for militias, not individuals, could vote to change the law, perhaps for decades, perhaps for the entire rest of my children's lifetimes. And my worries about putting my children on the school bus would be much more about whether the bus would crash or some mean kid would bully them than about whether they'd come home in a body bag. And my children would only have to worry about whether my grandchildren would be able to transport themselves home safely at the end of the day instead of whether those grandchildren would fall to the floor in some public school classroom, full of bullet holes.
