Following a series of incidents with bombs hidden in air cargo in November 2010, European Union (EU) Counterterrorism Coordinator Gilles de Kerckhove circulated two discussion papers in which he informed the Council of the European Union about the ongoing challenge of the security of transportation. “Much has been achieved in transport security in recent years”, he pointed out, and yet “the threat keeps getting more and more diverse” (Council of the European Union 2010a, 2). While the occasion for publishing the reports was the threat against civil aviation, de Kerckhove took the opportunity to call the Council’s attention to land transport security and to the security of mass transport security, in particular. In the report, he points out that “more has to be done on the less protected area of land transport”, now that “there is the obvious risk that as aviation becomes increasingly more secure, terrorists might switch to targeting land transport, e.g. to strike rail access to airports or multimodal hubs” (Council of the European Union 2010a).
