RT Article T1 Police-community engagement and the affordances and constraints of social media JF Policing and society VO 31 IS 4 SP 373 OP 385 A1 Bullock, Karen A2 Garland, Jon A2 Coupar, Freya LA English YR 2021 UL https://krimdok.uni-tuebingen.de/Record/175768560X AB This article provides an analysis of the ‘affordances’ and ‘constraints’ of technology-mediated police-community engagement in the United Kingdom (UK). Whilst there has been optimism that social media may transform police communicative practice and help democratise policing, studies suggest that this potential has yet to be realised. Drawing on in-depth interviews with communications professionals, the article demonstrates that social media may afford constabularies visibility, editability, and association. However, organisational, individual and technological factors influence whether these affordances are achieved. This article adds to the literature by demonstrating how citizen engagement with mediated communication is not inevitable. It is instead a product of what the technology affords, the relationship between the technology and its users, and the context within which it is used.
