On the new ‘Beat the Press,’ we look at the week in media, starting with Don Lemon’s arrest

On the new “Beat the Press with Emily Rooney,” we look at Don Lemon’s arrest, when journalists should (and shouldn’t) use the word “murder,” looming cuts at The Washington Post, and transitions for Scot Lehigh, who’s retiring from The Boston Globe, and David Brooks, who’s moving from The New York Times to The Atlantic. With Emily, Scott Van Voorhis and me — plus a big assist from producer Tonia Magras.
