                  The dashboard shows the median officer response time is four minutes and 54 seconds for incidents involving ShotSpotter. It shows gunfire incidents by day of week and time of day. There is also a map of where the incidents occurred.

                  The data also shows where ShotSpotter makes mistakes. As of Tuesday, the dashboard showed:

                  • 11 false positives: A non-gunshot incident incorrectly classified as gunfire based on the review by ShotSpotter personnel, and improperly alerted to Durham police.
                    • Eight false negatives: A gunshot incident incorrectly classified as non-gunfire based on the review by ShotSpotter personnel or automatically dismissed by the system, and not alerted to Durham police.
                      • One duplicate: A gunshot incident incorrectly duplicated and alerted to Durham police multiple times.
                        • One mislocated: A gunshot incident incorrectly alerted to Durham police at the wrong location.
                          • One missed: A gunshot incident incorrectly determined by the ShotSpotter system to be non-gunfire) (machine classified) and not presented to a human reviewer for classification

                            The dataset used in the dashboard will not include ShotSpotter alerts that happened on New Year’s Eve, New Year’s Day or Independence Day.

                            The city plans to update the dashboard each week.

                            Durham leaders launched their one-year pilot program using the controversial technology in mid-December.
