New York police used employed Clearview AI facial recognition technology to track down Derrick Ingram, a 28-year-old BLM activist, prompting controversy.

Accused of shouting into a police officer's ear with a bullhorn during a 2020 Black Lives Matter (BLM) protest, NYPD officers traced Ingram to his apartment, outside of which they were seen examining a document titled "Facial Identification Section Informational Lead Report," which contained a photo of Ingram apparently taken from his Instagram account.

The NYPD confirmed using facial recognition in the investigation, stating it was used as a "limited investigative tool." However, using a social media photo potentially violated their own policies, which limit the use to surveillance video stills or arrest photos.

The incident raised concerns about the NYPD's use of facial recognition technology to target activists and protesters. 

Critics argue that the use of facial recognition for identifying protesters could have a chilling effect on freedom of assembly and disproportionately affect Black and minority communities.
