Waze a danger to cops? Police reveal their own location on social media

Los Angeles police Chief Charlie Beck has been vocal in his concerns about the Google-owned Waze app and its feature that allows users to point out where police are. But LA police themselves often reveal their location on social media.

It's referred to as predictive policing information. Police elect to reveal the presence of officers by way of Twitter or other social media, and officers are aware. But, Beck said sometimes the public should not know where police are. "It is not always in the public’s best interest to know where police are operating," he said. Motorists might disagree.
