The shocking video of a South Carolina cop firing eight shots and killing a man he'd pulled over in a routine traffic stop ignited intense outrage online, including social media posts from several boldface names.  “No-spin video clearly shows white N. Charleston cop shooting fleeing black man 8 times in the back,” TV anchor Geraldo Rivera tweeted Tuesday night. “If this guy’s acquitted I’ll join protest,” he wrote, referring to Michael Slager, the officer charged Tuesday with the murder of Walter Scott.  S.C. COP MICHAEL SLAGER CHARGED WITH MURDER OF WALTER SCOTT  R&B artist Janelle Monae wrote the video “brought tears to my ears,” and “The Avengers” director Joss Whedon compared the killing to “a mafia thing, like it’s meant to shut people down or set them off. IT HAS TO END.”  Rapper Big Boi simply tweeted an image of the hashtag “#WalterScott,” which was the top trending topic on Twitter Tuesday night.  EDITORIAL: THE CRIMINAL KILLING OF WALTER SCOTT  Questlove went on a brief Twitter rant apparently inspired by the video, which he didn't directly reference.  "i believe in waiting to hear everything before casting opinion. but allow me the preemptive...uh...shot of 'i feared for my life' my ass," the musician wrote. "can you imagine the amount of murders that went down before the age and development of cell phone videos? this didn't start this year."  Slager initially said he had feared for his life because Scott took his stun gun, but the video captured by an onlooker showed an apparently unarmed Scott trying to run away.  WALTER SCOTT 'USED FOR TARGET PRACTICE' BY COP: BROTHER  South Carolina Sen. Tim Scott, who hails from North Charleston, also added to the online outrage, tweeting a two-part statement about the case.  “After watching the video, the senseless shooting and taking of #WalterScott’s life was absolutely unnecessary and avoidable,” Scott wrote.
The shocking video ignited intense outrage and grief from notable names online, with one celebrity vowing to take a stand in the case.
