EU expansion has stoked fears that criminals from the East may abuse freedom of movement to exploit the benefit systems of richer states. This book examines the way in which physical state borders are increasingly being replaced by internal border controls in the form of state bureaucracies as a means of regulating westward migration. The work examines the postmodern effect of globalisation and how ontological anxieties contribute to securitisation and social sorting in Western countries. It discusses the changes in control societies and how targeted surveillance as a geopolitical tool leads to new digitalised mechanisms of population selection. The book presents a casestudy of Roma migrants in the UK to examine the coping strategies adopted by those targeted. The book also critically evaluates the limitations of digitalised bureaucratic systems and the dangers of reliance on virtual data and selection methods.
