Peter Kadzis flies solo in this episode, talking with WGBH News contributors Dan Kennedy and Harvey Silverglate about their annual compendium of threats to, or diminishments of, free speech. Some big names in this year’s edition: Massachusetts Attorney General Maura Healey, Boston Police Commissioner Bill Evans, former President Barack Obama, and President Donald Trump — plus UMass Boston, Tufts, and Northeastern. Take a listen, and then read Kennedy's and Silverglate's pieces here and here.
