Whether district courts are misapplying the 'relevant-conduct' section of the United States Sentencing Guidelines

QUESTION(S) PRESENTED The United States Sentencing Guidelines directs courts to use uncharged offenses in its calculation of a defendant's guideline range if the uncharged offenses constitute "relevant conduct" under U.S.S.G. § 1B1.3. The Sixth Circuit Court of Appeals held that possession of firearms in You Tube music videos constituted "relevant conduct", notwithstanding the fact that each music video is separated by approximately a year, as well as the fact that there is no common purpose or similar modus operandi between the uncharged conduct and the instant conviction. Are district courts being allowed to overreach and misapply the "relevant conduct" section of the Guidelines?
