Mayor Bill de Blasio expressed his condolences to the family of two murdered NYPD officers while asking the public to put aside protests and political demonstrations during a period of grief. "It was an attack on our democracy, our values, and an attack on every New Yorker, and we have to see it as such," de Blasio said at a police charity event on Monday. De Blasio urged the public to stand by the families of officers Rafael Ramos and Wenjian Liu, both fatally shot execution-style on Saturday in Brooklyn by gunman Ismaaiyl Brinsley. "We all see the world through the prism of our own families," he said.
