Allmendinger and Oncale ran an investment scam that imposed $100 million in losses on 800 investors.

Allmendinger did not cooperate when the scam was investigated; he received 45 years in prison under the Sentencing Guidelines. Oncale cooperated in the investigation and received 10 years in prison. Allmendinger appealed, contending that as they committed the same crime the sentences should not be so different. Is that position correct?
