Digital connectivity has transformed daily life, offering tools like Google Maps and Siri that make navigation seamless. Fitness trackers, smart appliances, and home security systems such as Nest cameras or Amazon Echo have become commonplace. Yet this convenience comes with a hidden cost: the constant generation of personal data. Legally, it remains ambiguous when and how this information might be leveraged against individuals by police and courts.
Andrew Guthrie Ferguson, a law professor at George Washington University, addresses this complex issue in his latest work, Your Data Will Be Used Against You: Policing in the Age of Self-Surveillance. An authority on emerging surveillance tech and criminal justice, Ferguson previously authored The Rise of Big Data Policing in 2018, which analyzed early data-driven policing experiments, predictive models, and new camera surveillance forms.
In his new book, Ferguson zeroes in on what he terms self-surveillance—the data individuals produce through devices that can lead to incrimination. He points to a regulatory void: few laws govern how law enforcement accesses and utilizes this information. “I liken this sort of police-driven self-surveillance to democratically mediated self-surveillance,” Ferguson explained. “It’s still self-surveillance with our tax dollars and everything else, but we are also creating nets of smart devices and surveillance devices in our homes, in our cars, in our worlds.”
Ferguson argues that society has not fully grasped how this data can serve as evidence, potentially wielded for beneficial or harmful purposes based on political shifts. “And I don’t think we’ve really processed how all of that information is available as evidence and can be used against us for good or bad, depending on the sort of political wins and whims of who’s in charge,” he stated. “We’re seeing today how that vulnerability can be weaponized by a government that wants to use it.”
