ABSTRACT
This chapter highlights the requirement for mass data collection and pre-emptive legislative measures aimed at reducing the terrorist threat. It describes that the pre-emptive measures include temporary travel restrictions and the criminalisation of neutral behaviour, such as the collection of data deemed to be useful to a terrorist. Although the chapter highlights the connection between the risk society theory and predictive policing, it remains within the legal research framework, discrediting terms used such as 'mass data surveillance' and 'pre-crime'. The chapter shows that data retention is not the same as mass surveillance and that 'pre-crime' is a fabricated term used misleadingly, given that pre-emptive measures are in fact criminal offences. Islamist or Jihadi tourism brings with it its own danger, serving to not only increase independent operational abilities but also provide extensive hands-on military training in the use of firearms and explosives.
