Your Digital Trail, And How It Can Be Used Against You
While the collection of private information by the National Security Agency is under scrutiny worldwide, a remarkable amount of your digital trail is also available to local law enforcement officers, IRS investigators, the FBI and private attorneys. And in some cases, it can be used against you.
This week, NPR and the Center for Investigative Reporting are documenting just how vivid the typical person's digital picture has become — and how easy it can be for others to see it.

Exactly what kind of data can be obtained with a search warrant is still relatively uncertain. Schulz and Zwerdling cite, for example, a case in which police obtained seven months' worth of location data from the cellphones of two robbery suspects — without a warrant.
Even unopened emails are up for grabs:
The takeaway? While there are some measures you can take to prevent the government and others from monitoring your data and movements, much of what we do online and in public spaces can be used, sold and shared to create a remarkably detailed portrait of our lives.
