U.S. v. Rigg

Dist. Ct. did not err in imposing mandatory minimum sentence of 15 years under Armed Career Criminal Act (ACCA) on charge of possession of firearm by felon, even though three prior felonies used to support instant sentence occurred more than 35 years prior to instant offense. Ct. rejected defendant's arguments that imposition of instant mandatory minimum sentence violated separation of powers doctrine, his 5th Amendment due process rights, his 6th Amendment right to jury trial and 8th Amendment where defendant presented evidence demonstrating rehabilitation since date of prior convictions. Fact that instant prior convictions involving separate armed robberies occurred within 6-day window did not require different result.
