It demonstrates that despite predominantly negative perceptions about and experiences with the police, local residents do not abandon state institutions as security providers. The article claims that as formal and informal access to the legal and coercive powers of the police provides an important resource for local residents needing to resolve individual or collective security problems and conflicts in their favour, local police forces continue to be addressed and imagined by residents as relevant security actors.
