Police data could be labelling 'suspects' for crimes they have not committed

Several US law enforcement agencies use analytics software to identify potential criminals, yet there is little oversight and no proof the data is reliable

A police officer stands at the corner of a busy intersection, scanning the crowd with her body camera. The feed is live-streamed into the Real Time Crime Center at department headquarters, where specialized software uses biometric recognition to determine if there are any persons of interests on the street.

Data analysts alert the officer that a man with an abnormally high threat score is among the crowd; the officer approaches him to deliver a "custom notification", warning him that the police will not tolerate criminal behavior. He is now registered in a database of potential offenders.
