![]() The color of the box tells her what kind of crime is most likely to occur-for example, robberies, assaults, or property crimes. When Officer Raper logs into the system on her patrol car laptop, she sees different boxes to choose among. The recommended patrol strategies may differ based on recent crimes in the area, the time of day, and the prevalence of certain types of businesses, such as liquor stores, or geographical locations, such as bus stops. ShotSpotter Connect breaks down cities into “boxes”-typically several hundred feet square-and recommends patrol strategies for those areas. The ShotSpotter system, called Connect, uses that data to create a risk assessment of where crimes are most likely to happen that day, making it possible for police departments to allocate their resources in the most efficient manner. It ingests and analyzes a large amount of data that is now available to police departments-including gunshot locations, past crime records, time of day and day week, housing and population density, upcoming events, and the like-and recommends directed patrols for particular police officers or teams. The other AI system for policing that Officer Raper uses recommends a “ next best action”-similar to those used in marketing-to patrol officers.

Officer Raper thinks that the gunshot system is a great aid to her and other officers in finding people who shoot guns. This entire process takes less than one minute from the time of the shooting to the digital alert popping onto the screen in the Wilmington PD’s STING (Situational Tactics and Intelligence Nexus Group) center, and a few more seconds to appear on Officer Raper’s mobile laptop or phone. ShotSpotter supplements the gunshot alert and location with other information, such as whether an automatic weapon was fired or whether there are multiple shooters. Acoustic experts in ShotSpotter’s 24x7 Incident Review Center ensure and confirm that the sounds are actually gunfire many sounds that are deemed by the algorithms as not gunfire do not have to be presented to the human experts.
