U.S. v. Vaughn

Dist. Ct. did not err in sentencing defendant to above guideline, 180-month term of incarceration on charge of aggravated assault on prison guard. Dist. Ct. adequately explained rationale for giving above-guideline sentence where Dist. Ct. made accurate calculation of appropriate guideline range and indicated that higher sentence was necessary to deter senseless attack involving defendant's use of gruesome shank to stab victim several times.
