“…After one and halfcentury later, during 20 years, from clarifying the role of the 'police-state' to protect state and community by Chapman (1970) to its specialised arguments about 'what works' in community policing by Sherman (1986), we have been looking for the best productive and effective model to balance policing and police response in crime prevention, unfortunately, both of them did not predict what should police to conduct their community policing in health crisis like COVID-19 pandemic now (van Dijk and Crofts 2017, Punch 2019, van Dijk et al 2019. Very different to democracy states such as Canada, the U.K., and U.S. where permits and calls 'private security could take over protecting hospitals and other critical institutions' (Luna et al 2007, p. 13), VPF has to escort and protect these locations as one of the mandatory duties to ensure 'nothing-in-nothing-out' during lockdown (Luong et al 2020). In other words, in Vietnam, police play as central role in 'intensive teams' to conduct these duties and the case of Truc Bach's cluster is one such typical evidence to illustrate the continuous presences of police at the Hong Ngoc's International Hospital when applying isolation plans.…”
