Denver Broncos linebacker Brandon Marshall has been vocal about his decision not to stand during the national anthem, explaining to reporters that he’s doing so as a way to raise awareness about racial inequality in America.

On Tuesday, Marshall was asked about the video circulating that shows Terence Crutcher, a black man from Oklahoma, getting shot and killed by Tulsa police. Here’s what Marshall told Nicki Jhabvala of the Denver Post.

“I did see the Terence Crutcher video. It’s very saddening, especially to hear someone in the helicopter say, ‘That looks like a bad dude.’ How does that look like a bad dude? You’re way up in the air. That’s something that’s disturbing, but that’s exactly the reason we’re protesting.”

In the video, Crutcher’s hands were raised in the air as he walked slowly toward his car. He appeared to be leaning against his vehicle as officer Betty Shelby fired the fatal shot.

“Looks like a bad dude,” one officer in a helicopter could be heard saying in the video. “Could be on something.”

A Tulsa Police official told the Tulsa World Tuesday afternoon that PCP was found in Crutcher’s vehicle.

The U.S. Department of Justice has opened an investigation into the case.
