Mayor Bill de Blasio and Police Commissioner William Bratton both took part Friday in a ceremony honoring fallen New York City police officers.
Thirteen names were added to a memorial wall at One Police Plaza.
The mayor said the ceremony served as a reminder of the dangers that officers face in their daily lives.
The two also talked about the importance of community, both throughout the city and within the department.
"You represent what is best about New York City. You represent what is best about all the neighborhoods and communities you come from," de Blasio said. "But unlike most citizens, you risk your lives every day for your fellow New Yorkers."
"I think all of you in this audience understand what I mean about that second family," Bratton said. "The men and women, their partners, their friends, their colleagues who were there for them in life and remain there for them in death."
Twelve of the 13 names added to the memorial wall were officers who died from September 11th-related illnesses.
The other was Officer Dennis Guerra, who died from injuries he suffered responding to a fire in Coney Island last month.
