There's been a lot of yammering lately about facial recognition in criminal justice. So much noise that developers like IBM have walked away from facial recognition and agencies across the world are getting in hot water over its adoption & use.
Face Recognition Policy Development Template
The DOJ's Bureau of Justice Assistance (BJA) published a policy template for LE agencies back in 2017 that you may find helpful. Of particular note is the recommendation that the technology only be used for investigative leads, and that facial recognition results on their own do NOT establish probable cause and should NOT be considered positive identification.
Common sense, many might say, myself included.
Make it a great day, my friends!
