Dean v. United States

Dean (defendant) robbed a bank while carrying a gun that accidentally discharged; he was convicted of the underlying robbery and a federal gun-enhancement charge carrying escalating mandatory minimums depending on whether the gun was carried, brandished, or discharged, and the district court imposed the ten-year mandatory minimum for discharge. Dean appealed, arguing the enhancement shouldn't apply since he never intended to fire the gun; the Eleventh Circuit affirmed, and the Supreme Court granted certiorari.
