(New York Times) Forty inmates lined up for the daily mail call at the Fort Dix Federal Correctional Institution, a complex of low-slung brick buildings in the middle of New Jersey. It was July 2012, and one of the inmates was Philip Baker. A former hedge fund manager, he was serving a 20-year sentence for fraud. He had used bogus performance data to lure hundreds of people and institutions into his fund. His investors had lost hundreds of millions of dollars.
