Victor Henderson pled guilty to conspiracy to possess with intent to distribute 50 grams or more of cocaine base from January 1, 2001 through August 30, 2003, in violation of 2Í U.S.C. § 846. Based on Henderson’s prior convictions, the presen-tence investigation report calculated Henderson’s criminal history at category V. The district court 1 found that category V substantially over-represented the seriousness . of Henderson’s criminal history. Departing downward, the district court sentenced Henderson as a category IV offender and imposed a sentence of 188 months’, imprisonment and 5 years supervised release. We affirm.
Henderson argues on this appeal, as he did in the district court, that because of
Blakely v. Washington,
When Henderson was sentenced, the United States Supreme Court’s decision in
United States v. Booker,
— U.S. -,
It is undisputed that the prior sentences used to determine Henderson’s criminal history level were separated by intervening arrests. Thus, the district court did not make any factual findings which run afoul of the Sixth Amendment in determining that Henderson’s prior sentences. were unrelated. The non-constitutional Booker violation in this case, i.e., the district court’s failure to treat the Guidelines as advisory, was harmless as Henderson received a downward depar *1080 ture to a reasonable sentence. The district court’s sentence is affirmed.
