ABSTRACT
Terrorism, and the measures taken by security services against it, once stood firmly outside the precincts of criminological scholarship. In the wake of the attacks on New York and Washington, DC in September 2001, and subsequent attacks in Bali, Madrid and London, that changed rapidly. The radical changes brought about by the new threat of global terrorism, by anti-terrorist measures brought in to counter that threat, and the expanding role of the security services all became subjects of criminological enquiry (Walker 2004, Deflem 2004). This is hardly surprising, for the new security policies have had significant knockon effects on criminal justice values and practice and the subsequent development of criminal policy (Valverde 2001, Walker 2004).
