ABSTRACT
This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book describes the use of technology in the investigative stage of the criminal process. It notes that digital technology has led to an exponential increase in the amount of biometric data taken and created by law enforcement agencies. The book considers the unique rights impacts of automated facial recognition technology when it is used to monitor children, by drawing on relevant privacy and criminal law scholarship. It offers a front-line policing perspective on the impact of new technologies, and explains the multifarious impacts of body-worn camera (BWC) technology on policing. The book compares different approaches to protecting privacy and personal data in the European Union and the United States through reference to police use of BWCs. It addresses privacy issues that arise in respect of the publication of information relating to criminal investigations, trial proceedings, and the outcomes of the criminal trial.
