“We don’t do good TV. We do the news,” might as well be the slogan for “The Newsroom” Season 3. A new trailer, which originally debuted at TVLine, reveals that Aaron Sorkin will take on the Boston Marathon bombings — “social media’s gonna solve this crime!” — and a Wikileaks-type scandal.

“The Newsroom” returns for six episodes Sunday, Nov. 9 on HBO.
