Ruth Glenn knows from harrowing personal experience the danger of putting a gun in the hands of a violent spouse or partner, the issue at the heart of a case before the Supreme Court.

On a beautiful June evening in 1992, Glenn was shot three times, twice in the head, and left for dead outside a Denver car wash.

The shooter was her estranged husband, Cedric, who was under a court order to stay away from Glenn. But there was no federal law on the books at the time that prohibited him from having a gun.
