Say that you're walking down the street and that two robbers hit the cellphone store across the street. One of the robbers is shot, they leave the store and the bullet-catching robber goes to the ER. Then, two days later, the cops contact you and ask if you saw anything.
How did they know you were there? They did a "geofence warrant" and asked Google for information of anyone nearby the scene of the crime. Bet you have Google Maps or Waze or any other app that uses Google Maps on your phone. Most people do.
You can avoid that happening, if you choose. One way is to shut off location services. A more user-friendly way is to ensure that your apps use location services only when they're open on your phone (you do routinely closebackground apps, don't you).
