U.S. v. Duncan

Dist. Ct. did not err in denying defendant's section 3582(c)(2) motion to reduce defendant's 174-month term of incarceration on charge of drug conspiracy to distribute crack cocaine after finding that defendant was responsible for in excess of 4.5 kilograms of crack cocaine, since said calculation would not have changed defendant's offense level under new guidelines. Ct. rejected defendant's claim that Dist. Ct. impermissibly made new findings in instant proceeding in order to attribute 4.5 kilograms of crack cocaine to him, or that record did not support Dist. Ct.'s calculation of said drugs.
