For more than two decades — first at the Boston Phoenix, and now at WGBH News — Dan Kennedy’s New England Muzzle Awards have chronicled threats to the First Amendment and freedom of expression in our fair region. But reading the 2020 Muzzles (as you should!) is one thing; hearing Dan talk about the worst of the worst with Peter Kadzis and Adam Reilly is something else entirely. In this episode of the Scrum, the trio talks through the past year’s lowlights, which involve the Milton Public Schools, the Baker Administration, and Harvard University.
