Extended sentence review discussions in Sixth and Ninth Circuits

For whatever reason, Wednesdays tend to be busy days in the circuit courts, and today's sentencing action includes two lengthy opinions affirming lengthy sentences in the Sixth and Ninth Circuits.  In both opinions noted below there are extended discussions of both guideline-calculation issues and reasonableness review dynamics:

• US v. Erpenbeck , No. 06-4247 (6th Cir. July 2, 2008) (available here)
• US v. Warr, No. 07-30125 (9th Cir. July 2, 2008) (available here)

Both opinions make for interesting reads, though the Warr facts and legal issues are a bit more exciting because the case involves a defendant described by the sentencing court as a "borderline psychopath pyromaniac."
