"Welcome everybody to National Night Out," Mayor Bill de Blasio said.

And incoming commissioner O'Neill knows it best, vowing Tuesday night to continue to expand community policing so that cops on the beat will know the community because they work in it every day.
"They'll know the people calling 911, they'll know the people calling 311, they'll know the residents, they'll know the people that have businesses and we can have that connectivity," Chief O'Neill said.
Retiring Commissioner Bill Bratton sent a message to the NYPD rank and file, telling them how important their work is.

"One of the gifts he gave me was a key to the city, he didn't tell me that he'd already changed the locks," Bratton said.
