In page Omaha race riot of 1919:

"

It was at this moment that Marshal Eberstein, chief of police, arrived. He asked leaders of the mob to give him a chance to talk to the crowd. He mounted to one of the window sills. Beside him was a recognized chief of the mob. At the request of its leader, the crowd stilled its clamor for a few minutes. Chief Eberstein tried to tell the mob that its mission would best be served by letting justice take its course. The crowd refused to listen. Its members howled so that the chief's voice did not carry more than a few feet. Eberstein ceased his attempt to talk and entered the besieged building.[citation needed]
