Sentencing for acquitted conduct

1. Whether the Fifth and Sixth Amendments permit a federal sentencing court to rely on conduct underlying a charge of which the jury acquitted the defendant when that conduct supplies the factual basis for the punishment imposed, or whether United States v. Watts should be overruled or limited? 2. Whether, in a § 846 drug-conspiracy prosecution triggering § 841(b)(1)(A)'s ten-year mandatory minimum, a general guilty verdict may be treated as an individualized drug-quantity finding where the verdict form contains no separate quantity finding, the alleged drugs were concealed inside sealed, opaque containers, and the jury acquitted the defendant of possessing with intent to distribute those same drugs?
