This innovative volume explores issues of law enforcement cooperation across borders from a variety of disciplinary perspectives. In doing so it adopts a comparative framework hitherto unexplored; namely the EU and the Australsian/Asia-Pacific region whose relative geopolitical remoteness from each other decreases with every incremental increase in globalisation. The borders under examination include both macro-level cooperation between nation-states, as well as micro-level cooperation between different Executive agencies within a nation-state. In terms of disciplinary borders the contributions demonstrate the breadth of academic insight that can be brought to bear on this topic. The volume contributes to the wider context for evidence-based policy-making and knowledge-based policing by bringing together leading academics, public policy-makers, legal practitioners and law enforcement officials from Europe, Australia and the Asian-Pacific region, to shed new light on the pressing problems impeding cross-border policing and law enforcement globally and regionally. Problems common to all jurisdictions are discussed and innovative 'best practice' solutions and models are considered. The book is structured in four parts: Police cooperation in the EU; in Australia; in the Asia-Pacific Region; and finally it considers issues of jurisdiction and due process/human rights issues, with a focus on regional cooperation strategies for countering human trafficking, organised crime and terrorism. The book will be of interest to both academic and practitioner communities in policing, criminology, international relations, and comparative Asia-Pacific and EU legal studies.
