The Tenth Circuit affirmed the district court’s imposition of a six-month prison sentence and one year of supervised release following the revocation of Darrel Bailey’s supervised release for failing to register as a sex offender. The court held that Bailey failed to demonstrate the sentence was substantively unreasonable under an abuse of discretion standard. Applying the legal test from *United States v. Carter* and 18 U.S.C. § 3553(a), the panel determined that the district court did not act arbitrarily, capriciously, or manifestly unreasonable in balancing the sentencing factors. The appellate court noted that the district court expressly considered Bailey’s arguments regarding his age, mental health, and low risk of recidivism, while also weighing his unrepentant refusal to comply with registration laws as an aggravating factor. Because the sentence was well below the applicable Guidelines range, it was presumed reasonable, and Bailey offered no specific evidence to rebut this presumption or justify a lower variance beyond a request for the appellate court to re-balance the factors de novo. Consequently, the judgment of the district court remains in effect, and Bailey must serve the imposed term.
