Airman's conviction for first degree murder, attempted murder, second degree robbery, assault with a firearm and numerous off-base offenses is affirmed over claims that: 1) the trial court erred in denying defendant's motion to suppress evidence that was the product of two warrantless searches of his on-base living quarters; and 2) the prosecutor committed prejudicial misconduct in closing argument by denigrating the reasonable doubt standard to a mere "reasonable decision."
