Court of Appeals for the First Circuit April 19, 2016, No. 14-1976 (United States v. Rodríguez-Milián)

SELYA, Circuit Judge.

A party who fails to preserve potential claims of error in the trial court usually encounters strong headwinds on appeal. *30So it is here. Concluding that the appellant’s asseverational array is largely un-preserved and wholly unpersuasive, we affirm his conviction and sentence.
