¶9 Kaster next argues that the evidence was legally insufficient to sustain the disorderly conduct charge. …. Kaster has not demonstrated a “sufficient reason” under § 974.06(4) to overcome the fact that he failed to raise his challenge on direct appeal. See State v. Escalona-Naranjo, 185 Wis. 2d 168, 181-84, 517 N.W.2d 157 (1994). Thus, Kaster is procedurally barred from raising the disorderly conduct conviction now.
