The protesters signs say “No hay justicia, no hay paz”
Better would be “No dinero, no paz.” (No money, no peace.) That’s how unions operate in any language.
That is a statement that threatens violence and murder if they do not get their way. It started during the Rodney King riot, and Maxine "Kerosene" Waters led the mobs in that chant.
She should have been arrested for inciting riots, but she wasn't.
