(Undated) -- Governor Corbett has treaded carefully when speaking about the allegations of child sex abuse against former Penn State defensive coordinator Jerry Sandusky.  At the first press conference where he answered questions about the Sandusky case, Governor Corbett warned reporters that he could not go into details of the grand jury investigation that began on his watch as state Attorney General. “Again, I can’t go into that right now.  I would love to.  I hope you all know I would love to.  But I can’t,” he said last week.  Lawrence Fox, a legal ethics lecturer at Yale Law School, says respecting grand jury secrecy means Corbett can’t hint at what he’d like to say.  “You can’t you know, get around it by saying something like, ‘I wish I could share with you all the really good stuff that’s in the grand jury,’ because now he’s breaching grand jury secrecy,” he says. Another ethics expert says Corbett can’t be expected to clamp down completely, as the commonwealth’s top official in a case that involves state law enforcement, state-funded institutions like Penn State, and Sandusky’s charity itself, recently discovered to have been slated to get state money.
