The bombs hurled during violent protests near Gracie Mansion on Saturday were real, highly volatile explosive devices, NYPD Commissioner Jessica Tisch said Sunday. “The NYPD Bomb Squad has conducted a preliminary analysis of a device that was ignited and deployed at a protest yesterday and has determined that it is not a hoax device or a smoke bomb,” Tisch wrote on X. “It is, in fact, an improvised explosive device that could have caused serious injury or death.”
