evidence: Disgraced former ABC News reporter James Gordon Meek — who traded "sadistic" child pornography content involving infants and toddlers — should get as much as 15 years behind bars at his sentencing later this week, federal prosecutors said. Meek, 54, is set to be sentenced Friday in Virginia federal court after he pleaded guilty in July to transporting and possessing child sex abuse material — and has asked the judge for the minimum of five years in prison. [...] The once-acclaimed national security journalist sent and received child porn materials of "infants and toddlers and content depicting sadistic and masochistic abuse of prepubescent children," the prosecutors wrote.
