When the first Key System streetcar rolled up to the police blockade early Sunday morning, police tried to move it through the gathering crowd. But the driver, Al Brown, an officer in the Amalgamated Transit Union Local 192, learned from the strikers what had happened. He removed the controls from the streetcar and left his vehicle standing in the middle of the street. Next Brown convinced the drivers of the streetcars behind him to do the same. Bus drivers passing through the area also halted their vehicles and joined the picket lines, which by now swelled with union sympathizers. A police three-wheeler ran over one streetcar driver, Newton Selvidge. He had to be taken to the hospital.
