#One person stabbed during massive Proud Boys brawl in DC

Violence erupted in Washington, D.C. Saturday night as Proud Boys and Antifa clashed after a day of pro-Trump demonstrations, leaving one cop injured and at least four people stabbed — including in this dramatic, caught-on-video knife-fight.

The video shows a lone African American counter-protester, dressed all in black, as he is surrounded outside Harry’s Bar at 11th and F streets NW by a group of shouting white men.

Many in the crowd are wearing “America Strong” hats and the gold, laurel wreath insignia associated with the far-right, white nationalist Proud Boys.

At first, the surrounding group just taunts the black-clad counter-protester, telling him to leave.

He indeed begins to walk off, glaring at the taunting group over his shoulder.

“Get out! Get the f— outta here!” they shout at him. “Go that way!” 

 But when he’s shoved from behind, the lone counter-protester pulls what appears to be a gravity knife from his right coat pocket.

He flicks it open and holds it down at his side as he continues trying to walk off — and the group surrounding him bursts into screams and shouts, some among them moving still closer to him.

“He’s got a knife!” they shout. Others in the crowd shout, “Get back! Get back!” 

Women can be heard shrieking. One woman is seen in the video grabbing and pulling at the counter-protester’s balaclava-style ski hat, which covers most of his head and face. 

The counter-protester appears to be swinging his knife and running away as some in the crowd give chase and then tackle him.

“Get his ass!” someone in the crowd yells.

“Stop guys stop — please stop” police can then be heard shouting as they try to break up the scrum, into which the knife-wielding counter-protester has disappeared.

The clip ends with the crowd clearing the way for multiple D.C. police officers, who rush to the scene, break up the scrum and take control of the now cowering counter-protester, who has curled up into a ball on the sidewalk.

A separate video of the same incident, tweeted by @mauricioxgomez, shows others in the crowd surrounding and trying to help a male victim with a bleeding stab wound to his stomach.

“He got stabbed!” someone shouts. “Medic! Medic! Medic!”

At least four stabbing victims were hospitalized, and some suffered life-threatening injuries, DC fire spokesman Doug Buchanan told the Washington Post.
