Mayor Zohran Mamdani is calling for a new Department of Community Safety following NYPD's recent response to mental health crisis in the city. Police say officers in Queens opened fire after a man pushed through a closed door holding a large kitchen knife. His family says they called 911 for medical help, not the police. Body cam footage of this incident was released on Jan. 26. The mayor says the incident shows the need for different mental health responses.
