Commentary
Statutory Provisions: 21
  U.S.C. §§ 859 (formerly 21 U.S.C. §
  845), 860 (formerly 21 U.S.C. § 845a), 861 (formerly 21 U.S.C. §
  845b).
Application Note:
1. This guideline applies only in a case in which the defendant is convicted
  of a statutory violation of drug trafficking in a protected location or involving
  an underage or pregnant individual (including an attempt or conspiracy to commit
  such a violation) or in a case in which the defendant stipulated to such a
  statutory violation. See §1B1.2(a).
  In a case involving such a conviction but in which only part of the relevant
  offense conduct directly involved a protected location or an underage or pregnant
  individual, subsections (a)(1) and (a)(2) may result in different offense levels.
  For example, if the defendant, as part of the same course of conduct or common
  scheme or plan, sold 5 grams of heroin near a protected location and 10 grams
  of heroin elsewhere, the offense level from subsection (a)(1) would be level
  16 (2 plus the offense level for the sale of 5 grams of heroin, the amount
  sold near the protected location); the offense level from subsection (a)(2)
  would be level 17 (1 plus the offense level for the sale of 15 grams of heroin,
  the total amount of heroin involved in the offense).
