This chapter explores thematic examples of police use of social media as image work to illustrate some of the ways that police seek to sustain the appearance of institutional legitimacy. Police image work is generally understood to encompass any activities that law enforcement agencies engage in to display meanings of policing. Drawing from and expanding upon some previously published work, the author explores police image work on social media as an illustration of David L. Altheide and John M. Johnson’s (1980) concept of “bureaucratic propaganda”. Unlike traditional understandings that often focus on propaganda as pejorative, bureaucratic propaganda instead consists of a rethinking of traditional propaganda to include the calculated use of official information by formal organisations like law enforcement. This chapter explores police use of social media as bureaucratic propaganda through the following questions: How do we understand it? How do we study it? And what does it mean? The chapter outlines a suitable methodology by which such an analysis is perhaps best done and concludes with a brief discussion of the implications of police image work on social media as bureaucratic propaganda.
