U.S. v. Tichenor

Dist. Ct. did not err in sentencing defendant to 300-month term of incarceration on armed robbery charges after finding that defendant was eligible for sentencing treatment as career offender based on his prior convictions for dealing hash oil and resisting law enforcement. Ct. rejected defendant's argument that career offender sentencing guideline is unconstitutionally vague, or that U.S. Sentencing Commission exceeded its authority in enacting current definition of crime of violence.
