Political and scholarly knowledge exerts a significant impact on our comprehension of security, identity, crime, radicalism, terrorism and related phenomena. While the influence of politics and contextual factors is omnipresent in our understanding of these issues among ordinary individuals, my eight-month-long ethnographic research conducted in the Rohingya refugee camps in Bangladesh reveals notable distinctions in their perceptions. In contrast to prevailing literature that predominantly focuses on elite perspectives on identity around security, radicalism, and terrorism, this chapter explores the understanding of everyday identity held by the refugee population. In particular, it underscores the refugees’ layman comprehension of fluid identities about themselves and other security actors in the camps, including the police and militant groups, illustrating some prevalent misconceptions that exist within the statist narratives regarding security and identity in the refugee camps. In so doing, it argues that a vernacular understanding of identities in the security domain is pivotal for deconstructing stereotypes that contribute to the existing knowledge of identities around (i) the refugee population (ii) radicalisation and terrorism in the refugee camps (iii) security actors such as police and other similar agencies.
