Police urge Google to turn off 'stalking' feature on mobile app for drivers (theguardian.com)

From my view, why this app is so popular around the world? It provides the users more information about the local traffic, and help users save a lot of time. I think the stalking feature is an important function for users. You know, in some countries, the police is always trying to give a fine to the drivers in order to make grey income. Drivers would avoid this with this app. The concern is about the safety of the police. I think the app could also make some changes and only show the police in 1 km rather than show the police location on the map. In this way, the criminals could not use the app for tracking police location.

I'm waiting for the legal argument. I think we all know the public can be talked into just about anything.
