U.S. v. Macias
Defendant waived his appeal on issue regarding Dist. Ct.’s imposition of two-level enhancement under section 2D1.1(b)(15)(D) of USSG for obstruction of justice based on finding that defendant had testified falsely at trial. Defendant failed to raise instant enhancement issue in his sentencing memorandum or in objections to presentence investigation report and neglected to raise issue at sentencing hearing, even though Dist. Ct. gave defendant opportunity to do so. Ct. further noted that defendant’s waiver of enhancement issue made strategic sense, since any challenge to obstruction enhancement could have tainted defendant’s mitigation argument about his personal history and family circumstances.
