A Seattle history teacher who was pepper sprayed during a peaceful Martin Luther King Day Jr. rally is suing the cops who allegedly attacked him. Newly released video showed a Seattle police officer pepper spraying Jesse Hagopian as he walked home from the Jan. 19 rally, his lawyer said. Hagopian, who teaches history at Seattle's Garfield High School, spoke at the event and was on the phone with his mom when the spray hit his eyes.
