for a moment of silence with the City Hall staff in honor of two New York police officers ambushed and killed on December 20. The moment of silence was at 2:47pm local time, which is the time officers Wenjian Liu and Rafael Ramos were shot and killed.“It’s a time of mourning for two good families and it’s so important that we all stand in solidarity with them,” de Blasio said. “Officer Ramos and Officer Liu believed in something, they believed in making this world better, they believed in making this city better. They gave their lives for the belief that we could do better, that we could come together, that we could keep people safe.” Credit: YouTube/NYC Mayor’s Office">
