In the hands of law enforcement, this data could be evidence. But at every other moment, the location data is reviewed by hedge funds, financial institutions and marketers, in an attempt to learn more about where we shop and how we live.

There is no evidence that if we allow it to continue to happen, the country will be safer or fairer.
