State v. Cromartie, ___ N.C. App. ___, 810 S.E.2d 766 (Feb. 6, 2018)

Because the defendant never asserted a constitutional double jeopardy violation before the trial court, he failed to preserve the issue for appellate review. However, to prevent manifest injustice, the court invoked Rule 2 and addressed the merits of the defendant’s claim.
