NY mayor’s plea for pause in rallies rejected

De Blasio and other politicians have called for a cooling of tensions after the officers were ambushed Saturday while sitting in their patrol car, shocking a city that had seen largely peaceful demonstrations over decisions by grand juries in New York and Missouri not to indict white police officers in the killings of unarmed black men.
Since Saturday, some activists have woven in protests against the killings of officers Rafael Ramos, 40, and Wenjian Liu, 32, into their rallies and vigils.
