Celebrities are speaking out after a South Carolina police officer was charged with murder in the shooting of 50-year-old Walter L. Scott on Tuesday.

The death was captured in a gruesome video, which shows the officer, who has been identified as Michael T. Slager, 33, firing at Scott, a black man, eight times as he fled after a traffic stop.

Slager claimed that he feared for his life after he got into a scuffle with Scott for his Taser. In the video, an item can be seen falling to the ground, though Scott immediately runs from the officer afterward.

Former Grey’s Anatomy star Isaiah Washington praised the actions of the person who recorded the incident on their cell phone.

“Okay, watching the #WalterScott video was horrible, but I think the brave person who captured the murder is a Hero and a Godsend #Truthdom,” he wrote on Twitter.

“I have 2 sons to raise in this country and this #WalterScott atrocity weakens my hope that they can survive in this Nation. Now what?” he added.

Avengers: Age of Ultron director Joss Whedon also Tweeted about his outrage over the shooting, writing: “At this point, the Slager murder seems like a message, a mafia thing, like it’s meant to shut people down or set them off. It HAS TO END.”

Added Sleepy Hollow star Orlando Jones: “As a former resident of SC (where my parents still reside) I will do everything in my power to make sure #WalterScott’s family gets justice.”

Scott had been stopped for a broken taillight, according to the Times. Slager was denied bond and is being held at the Charleston County Detention Center.
