Pondering personal privacy: a pragmatic approach to the Fourth Amendment protection of privacy in the information age

As technology with surveillance capacities has advanced, the debate over the rights of the citizenry to be free from governmental breaches of personal privacy has intensified. Within the United States, government actions legally challenged as intrusions into personal privacy have been analyzed under the Fourth Amendment, but Supreme Court rulings in such cases lack a clear and consistent rationale. Additionally, while more than a dozen federal privacy statutes have been enacted, each piece of legislation pertains to a specific type of information (e.g. driver’s license information, education records, and financial records). There is no overarching federal legislation which protects the individual’s private affairs from warrantless government inspection. A key issue underlying the scope of the debate and the variation in court decisions and public policies pertinent to invasions of privacy by government agencies is the lack of a clear and cogent definition of ‘privacy.’ By means of a review of the evolution of legal protections of privacy under the Fourth Amendment and a review of the evolution of technology with surveillance applications, it is suggested that there is a need for a sound operational definition of privacy. As a starting point for an informed and pragmatic dialogue on this matter, an operational definition of privacy built upon extant case and statutory law is provided.
