Since the 1800s, the United States Supreme Court has struggled to define the limits of the Fourth Amendment and adapt the scope of its protection to advances in technology. The new ways we use technology to interact, and the role such technology plays in society, create unique questions that judicial precedent based on old technology has trouble answering. Most recently, cell phones and mobile applications have changed the way millions of Americans communicate with each other, and access and store information. For years the government accessed this shared information through subpoenas without triggering the Fourth Amendment’s protection from unwarranted searches and seizures.
