A primary goal of this book is to examine, especially in the UK context, whether the responses that are now evolving are getting this balance right and how such a balance can continue to be struck or perhaps enhanced in the future. As a consequence, the book will investigate three aspects of this context. It will seek to assess the nature of responses by key public and private sector bodies in the UK post September 11 for preventing, pre-empting, countering and managing terrorist attack. It will assess the quality of response against a matrix of other factors (types of terrorist networks, tactics and targets of groups etc). And it will compare and contrast the UK's response with cognate states elsewhere (USA/EU).
