Whether the district court erred in summarily denying an evidentiary hearing on claims of ineffective assistance of counsel and whether the Eighth Circuit misapplied the standard for granting a Certificate of Appealability

1. Whether the district court erred in summarily denying an evidentiary hearing on claims that trial counsel was constitutionally ineffective for failing to call two prepared defense witnesses whose testimony was central to the defense. 2. Whether the standard for granting a COA under 28 U.S.C. § 2253(c), as clarified in Miller-El v. Cockrell, 537 U.S. 322 (2003), was misapplied by the Eighth Circuit, thereby precluding meaningful appellate review of substantial constitutional claims. li
