In the 2008 case of Christopher Michael Dean v. United States, the Supreme Court ruled that a trial judge could consider mandatory minimum sentences for firearm possession in determining an appropriate sentence for other charges. The defendant, Christopher Michael Dean, was convicted on robbery and firearms charges under federal law which required a consecutive seven-year minimum sentence for discharging a firearm during a violent crime or drug trafficking offense. In sentencing him to concurrent terms of imprisonment on the robbery counts, the District Court took into account this mandatory consecutive term and imposed lower sentences than it would have otherwise done so as not to exceed what it viewed as an appropriate overall punishment level. On appeal by Dean arguing that his sentence should be reduced because he did not intentionally discharge his gun during the robbery, both Appeals court and Supreme Court affirmed District court's decision stating that judges may take into consideration all aspects of behavior punished under federal law while imposing sentences.

In the dissenting opinion for the case of Christopher Michael Dean v. United States, Justice Stevens argued that a firearm discharge during a crime should not automatically result in an additional mandatory sentence if it was accidental or unintentional. He contended that Congress intended to punish only those who intentionally discharged a firearm while committing a violent crime or drug trafficking offense, and not those whose firearms were discharged accidentally. The majority's interpretation of 18 U.S.C §924(c), according to him, failed to consider this intent and instead imposed harsher penalties regardless of whether the discharge was intentional or accidental. This approach could lead to unjust outcomes where defendants receive longer sentences due purely to unfortunate accidents rather than their criminal intentions.
