The Hidden Role of Facial Recognition Tech in Many Arrests — from wired.com by Khari Johnson
The technology is spreading fast among police, and often wrong. But people charged with crimes are rarely told an algorithm came into play.

Excerpt:

Across most of the US, neither police nor prosecutors are required to disclose when facial recognition is used to identify a criminal suspect. Defense attorneys say that puts them at a disadvantage: They can’t challenge potential problems with facial recognition technology if they don’t know it was used. It also raises questions of equity, since studies have shown that facial recognition systems are more likely to misidentify people who are not white men, including people with dark skin, women, and young people.
