September 24, 2014 Holder Memo on § 851 Enhancements in Plea Negotiations. Notable lines: “An § 851 enhancement should not be used in plea negotiations for the sole or predominant purpose of inducing a defendant to plead guilty.” Holder is making sure his message on drug policies is heard loud & clear before he departs!
