While technology impacts these critical issues in policing, not all technology adopted by the police is likely to influence their relationship with the public. As such, this chapter closely examines the ways that several emerging technologies adopted by the police (i.e., body-worn cameras (BWC), aerial surveillance, visual surveillance, social media, mapping and crime prediction, and less lethal force technology) impact issues related to social control, accountability, and legitimacy. The current literature seems to indicate that some innovations such as BWCs enhance police accountability and legitimacy, and also expand social control. Other technologies such as aerial surveillance and conducted energy devices increase social control, and display a complicated or unclear influence over police legitimacy.
