Fred Bayles, a Professor at Boston University School of Journalism, is a hard man to talk to. Not because he’s unfriendly or isn’t interested in talking, but he’s got other priorities. During the semester, he’s generally got a desk phone attached to one ear, a cell phone on the other and his fingers on a keyboard. At the other end of the phones and on his email are his students who are on Beacon Hill (Boston) staffing BU’s Statehouse Program. They’re reporters covering government and politics for a dozen local newspapers, websites, and radio stations around the state. And Bayles is their editor/teacher/mentor.
