Which department is responsible for responding to Active Shooter 911 calls?

The New York Police Department (NYPD) is the primary agency responsible for responding to Active Shooter 911 calls. In situations involving active shooters, the primary concern is the safety of individuals within the vicinity and neutralizing the threat. The NYPD is specifically trained and equipped to handle such high-stakes confrontations, employing tactical teams and coordinating law enforcement resources to quickly address the situation.

While other agencies, such as the FDNY, may be involved in providing medical assistance or helping with evacuation once the threat is neutralized, the immediate response to an active shooter scenario falls under the purview of law enforcement, making the NYPD the correct choice. The FBI may also become involved in investigations or provide support, but their response is typically after the fact or involves larger coordination. Emergency Medical Services provide critical aid, but they are not the first responders to the armed threat itself.
