With no explanation, chose the best option from "A", "B", "C" or "D". by a State to prevent subsequent review by [federal courts] of a federal constitutional claim.” Ford v. Georgia, 498 U.S. 411, 423-24, 111 S.Ct. 850, 112 L.Ed.2d 935 (1991) (quoting James v. Kentucky, 466 U.S. 341, 348-49, 104 S.Ct. 1830, 80 L.Ed.2d 346 (1984)). Because I believe the waiver rule in the courtroom closure context was neither firmly established nor regularly followed by Minnesota courts when Crawford’s public trial claim was deemed waived, I respectfully dissent. When the Minnesota Court of Appeals heard Crawford’s appeal there was just one published appellate case, post Waller v. Georgia, 467 U.S. 39, 104 S.Ct. 2210, 81 L.Ed.2d 31 (1984), which employed the waiver rule in the context of a courtroom closure. See State v. Bashire, 606 N.W.2d 449, 452 (Minn.Ct.App.2000) (<HOLDING>). In State v. Anderson, No. C2-95-1087, 1995 WL

D.
