San Diego police say they are finding far more guns, including in the hands of felons, and more untraceable “ghost guns,” which are assembled from parts that sometimes come in prepackaged kits. They are often unregistered and untraceable.
Last year, San Diego, like the rest of the country, wrestled with increasing gun violence. Assaults involving guns were up, and more people are calling 911 to report hearing gunfire. And twice last year, alerts from ShotSpotter, a network of audio sensors said to detect gunfire, led San Diego police to discover the scenes of deadly shootings that no one had called to report.
