Bill Cosby’s sentencing hearing Monday will begin with testimony about his sex offender evaluation and, presumably, a fierce debate over whether the 81-year-old actor should be branded a sexually violent predator. The stakes are high given the lifetime counseling, community alerts and public shaming the designation would trigger. And it could become evidence in the defamation lawsuits filed against Cosby by accusers who say he branded them liars when he denied molesting them. Defense lawyers say the state’s latest sex-reporting law, despite several revisions, remains unconstitutional. “It’s the modern-day version of a scarlet letter,” said lawyer Demetra Mehta, a former Philadelphia public defender, “which I think is sort of an interesting philosophical issue at this time with the #MeToo movement, but also criminal justice reform.” Pennsylvania’s sex-offender board has examined Cosby and recommended he be deemed a predator, concluding that he has a mental defect or personality disorder that makes him prone to criminal behavior.
