Miami-Dade Commissioners Vote to Expand Use of Questionable Gunshot-Detection Technology
In 2012, Miami-Dade County became one of the first places to test a gunshot-detection technology called ShotSpotter, which uses acoustic sensors to alert police to gunfire. But after a year of the pilot program, the county abandoned the system over concerns about its effectiveness: Officers were able to confirm only 50 shootings of 1,000 supposedly detected by ShotSpotter, and the department couldn’t point to a single crime the technology helped solve.
