For a year now Nassau County, New York, police department has been using the ShotSpotter system, and the country police commissioner says the department has been able to handle shootings much more swiftly, and that in certain instances lives might have been lost if it were not for the technology; the system records the number of shots fired, whether the shooter was stationary or moving, and provides audio playback of each gunshot event; this information not only provides situational awareness for law enforcement officers prior to arriving at the crime scene, but it is also offers valuable evidence for post crime analysis and legal proceedings
