United States v. Tyson, No. 08-5477-cr (2d Cir. March 15, 2010) (found here)
Just a quick note. Tyson challenged his 65 year sentence, which resulted from the stacking of sentences for various offenses of conviction. On appeal, the Second Circuit found the sentence to be substantively reasonable even though it amounted to a life sentenced primarily because: (1) it defers heavily to district courts, who are largely responsible for determining sentence; and (2) the district court gave explicit reasons for the sentence imposed and the stacking.
