Understanding the Fourth Amendment Through the Lens of Technology

Abstract

This article proposes a framework for applying the Fourth Amendment to new surveillance technologies. Kerr argues that courts should maintain technological equivalence—the principle that the Fourth Amendment should provide the same level of protection regardless of the technology used—by translating traditional Fourth Amendment concepts into digital contexts. The article addresses challenges posed by GPS tracking, cell phone location data, email surveillance, and social media monitoring, providing a practical framework for courts navigating the intersection of constitutional privacy protections and rapidly evolving technology.

Key Findings

• Fourth Amendment doctrine must evolve to maintain equivalent protections across technologies
• The third-party doctrine needs revision in the digital age when vast personal data is shared with service providers
• Content/non-content distinctions may be more analytically useful than public/private distinctions online
• Courts should focus on the invasiveness of surveillance techniques rather than the technology used
