The present invention extends to methods, systems, and computer program products for validating and supplementing emergency call information removing private information. A Public Safety Answering Point (PSAP) receives an emergency (e.g., 911) call from a mobile device. Parts of the emergency call are processed to identify an emergency call location. Characteristics of the emergency call are combined with characteristics of other signals to identify an emergency call event, including an event location. The emergency call event is sent to the PSAP. Prior to receiving phase II data, and possibly even prior to receiving phase I data, the PSAP receives the event. The PSAP tailors dispatch of emergency resources responding to the emergency call based on characteristics of the event, including the event location. A privacy infrastructure spans signal ingestion, event detection, and event notification and protects the integrity of private information.
