Briefly, the case in point was about a man named John Angus Smith who traded a handgun for cocaine. The law under which Smith was charged provided for a much more severe penaltyknown as an enhanced penaltyif a gun was used in a drug-related crime than if no gun was involved. (In this case, the enhanced penalty was a mandatory thirty-year sentence; the unenhanced penalty was five years.)Justice Antonin Scalia argued that Smiths penalty should not be enhanced because he did not use the gun in the way that the writers of the law had in mind; he did not use it as a gun. Justice Sandra Day OConnor argued that the law requires only the use of a gun, not any particular kind of use. If you were a judge, would you vote with Scalia or with OConnor?
