An angry racist man who claims to be a U.S. Marine can be seen harassing and threatening a group of Black Lives Matter protesters and hammering them with racist abuse.

The man reportedly turned up at the BLM protest carrying a sign that said, “Police lives matter.”

When a BLM activist addressed him, the man gestured obscenely at the group, then crossed the street to confront them, pointing to his Marines trucker cap and said, “I kill, b*tch!”

“F*ck you, b*tch. You wanna run your mouth, I’ll put my fist right through your f*cking skull. F*ck you, and f*ck you, too, you b*tch,” he raged.

He became steadily more agitated and abusive, calling men in the BLM group “boy” and spewing threats.

“F*ck you, b*tch. You wanna run your mouth, I’ll put my fist right through your f*cking skull. F*ck you, and f*ck you, too, you b*tch,” he went on, before leaning into the camera and saying, “You f*cking n****r!”
