Instead, the district court sentenced Johnson to additional prison time because Johnson had violated the terms of his supervised release by possessing crack cocaine.

Therefore, the District Court ... considered rehabilitative goals only in determining the length of defendant’s sentence, not in determining whether to impose a sentence.”).

C: holding that a sentencing court is required by 18 usc  3583g to revoke the defendants term of supervised release  unless defendant could come under the exception in 18 usc  3583d
D: holding that supervised release provisions remained advisory after amendments to 18 usc  3583
