https://tech.newstatesman.com/news/police-frt > A facial recognition software ban on police body cameras will take effect in California at the start of 2020. A new law, which lasts for three years, bans the state’s police departments from using facial recognition software on body cameras. The ban could be extended upon expiration of the moratorium. Prior to the law’s passage, two California cities – San Francisco and Oakland – enacted similar bans. > Some law enforcement groups suggest that the ban will prevent them from using technology that could aid them in identifying crime suspects or missing persons. However, the state law’s writer contends it is important to prevent police body cameras from becoming 24-hour surveillance tools.
