Bloomberg: Twitter has been accused in a lawsuit by the widow of a man killed at a police training center in Jordan of knowingly allowing the Islamic State to spread its terrorist message through its service. Lloyd “Carl” Fields Jr. was killed with four others in a “lone wolf” attack at a police training center in November. “Without Twitter, the explosive growth of ISIS over the last few years into the most-feared terrorist group in the world would not have been possible,” according to the complaint.
