A large crowd of people is marching down a city street, with a large white balloon emblazoned with the words "SINPEEM Sindicato dos Professionais em Educação no Ensino Municipal-SP" (Teachers’ Union of Municipal Education – São Paulo). The crowd is diverse in terms of age and race. Some are carrying signs and waving red flags. A white police car with flashing red and blue lights is visible. The car is marked “POLÍCIA MILITAR” and the license plate is “EZX.” A second, dark grey police car is also visible. The street is lined with tall buildings.
