The ACLU has released the results of our public records requests to hundreds of police departments asking about their cell phone tracking policies. What we have learned is disturbing.

Yesterday we asked the Third Circuit Court of Appeals to consider our argument that law enforcement agents should have to obtain a warrant based on probable cause to attach a GPS tracker to a car and track its movements (you can read our amicus brief here).

In the case, the government suspected that Harry, Mark and Michael Katzin had robbed a number of Rite-Aid pharmacies. To confirm their hunch they attached a GPS tracker—without first going to a judge and getting a warrant—to Harry Katzin’s car. They used the GPS tracker to follow the Katzins when they traveled to another Rite-Aid, and arrested them shortly afterwards.

Apple has finally responded to the revelation that iPhone and iPads keep records of their users' whereabouts. We're glad that Apple has promised to change this practice. At the same time, nobody should think of this dust-up as some overblown quirk or mere bug, as Apple has portrayed it. This incident should be a wakeup call to Americans that we need to demand greater transparency and accountability from the companies that collect and use our personal information.

If we do not limit the use of automated license plate readers, it will represent a significant step toward the creation of a surveillance society in the United States.
