GPS and your privacy
Earlier today, in a big victory for privacy rights, the Supreme Court ruled in U.S. v. Jones that the government violated the Fourth Amendment when it attached a GPS device to Antoine Jones's car and tracked his movements continuously for a month without a warrant. The ACLU filed an amicus in the case.
This was a critical decision for defending the Fourth Amendment, which protects Americans from unreasonable searches. But even more significant, this was the first time in 20 years, the Supreme Court has had to consider the constitutionality of location-tracking technology.
As the court made clear, attaching a GPS device to a car and tracking its movements implicates the Fourth Amendment. Unfortunately, the government is likely to persist in arguing that the decision does not apply to tracking the location of cell phones.
Tell Congress: The government can't use our cell phones as tracking devices without a warrant. (Do not forward: This link will open a page with your information already filled in.)
From GPS tracking to wireless surveillance, the ACLU is making sure your rights are protected and your privacy is respected.
Today was a big first victory. Now, we need to keep pushing for better privacy laws.
Thank you for all you've done to push for better privacy laws. We're starting to see the benefits of all that hard work. We can see even more progress if we keep pushing forward together.
