In the periphery of Rio de Janeiro, gates are being installed at the entrance to streets, which means that access is being restricted to residents only. This research is a small-scale ethnographic study focussed on one small street, in a low income area of Rio de Janeiro, which generated 8.5 hours of recording of both spontaneous interactions (meetings held by residents) and interviews conducted by me. The street has recently had a gate and six cameras installed, which, according to residents, help improve security. This concern with security connects with a global, post 9-11, trend towards securitisation, a process whereby "a particular group or issue is said to present such a major risk - such an 'existential threat' - that it needs to be moved out of the realm of ordinary politics into the realm of exceptional measures" (Rampton, Charalambous, Charalambous, 2017:3). This means that everyday life becomes permeated by a concern with security, which has been transforming the landscape of the city, increasingly, into Surveillant Landscapes (Jones, 2017). In this paper, I analyse both the changes to ordinary life brought about by the gate and cameras, and how residents articulate their new everyday life in talk-in-interaction. I argue that the installation of the gate by residents (instead of the municipality) follows the principles of exceptionality and urgency guiding securitising measures, in a process I have termed "DIY-Securitisation". My analysis shows that the space of the street is reimagined as a closed condominium (Caldeira, 2020), largely considered a prestigious housing style. Thus, these gating practices, and the resulting change in people's ordinary lives, are connected to wider issues related to securitisation and neoliberal governmentality.
