Police are currently working in pairs to prevent any further ambushes, Parizek said.


Greene, who has a lengthy record including charges of assault and a DUI, was also known to area police for bringing a confederate flag to an Urbandale football game earlier this month, apparently in protest of the Black Lives Matter protest. Police removed him from the stadium after he flew the flag during the national anthem.

“I was offended by the blacks sitting through our anthem. Thousands more whites fought and died for their freedom. However this is not about the Armed forces, they are cop haters,” a user with Greene’s name wrote in the comments section of a YouTube video showing Greene holding the flag.


A second video uploaded to the same channel shows Greene outside the stadium, claiming he had been assaulted by people inside the stadium and by the officers who removed him. He accused the police of stealing his confederate flag and demanded the officers bring him back inside the game to identify his assailants, who he said hit him and grabbed at his flag during the anthem. The officers declined, telling him it was unlikely the complaint would go anywhere.

“You came just to fly the flag and possibly cause a disruption tonight,” one of the officers said. “You have to understand in the current social climate we’re in, when you fly a Confederate flag standing in front of several African American people, that’s going to cause a disturbance, whether you intended to or not.”
