"This book is a one-stop-shop for counter-terrorism law and practice in the United Kingdom. It is essential reading for scholars and practitioners of counter-terrorism law and practice in this jurisdiction and beyond. Encompassing the major political and military developments of the last decade including the British response to ISIS, it provides a comprehensive assessment the law in theory and practice, the growth of executive power, and the hardening of 'soft' measures such as the Prevent strategy. The book keenly observes counterterrorism trend lines and continues to defend the rule of law as the basis for any successful response to the threat of terrorism." -- Professor Fionnuala Ní Aoláin, KC (Hon), former UN Special Rapporteur on the promotion and protection of human rights and fundamental freedoms while countering terrorism"This new edition of this legal classic includes incisive commentary on legislation affecting matters from criminal investigations, offences and sentences to immigration laws and counter-extremism. It is an invaluable guide for practitioners to complex and frequently changing laws that includes helpful statutory appendices (including from seven new laws since the last edition) and original empirical data about the actual use of the state's multi-faceted measures. This work will enlighten policy-makers, scholars, students and the interested public about the deeper issues. It is written with admirable clarity and attention to detail while never losing sight of the larger implications or the high stakes of counter-terrorism.

" -- Kent Roach, Professor of Law, University of Toronto"The arrival of Professor Walker's new Handbook is a genuine event. For years the Handbook has been the go-to referencer and source of principled yet practical wisdom and comprehensive understanding of the choices faced by democracies like the UK in the face of terrorist threats. The book is written, with Professor Alan Greene, in the admirably rich and punchy style of previous Handbooks, so it is a pleasure to read. Professor Walker has never sacrificed on the altar of critical terrorism studies, but draws on the best of the academic tradition, whilst given due prominence of the role played by published policy, codes of practice, cooperation arrangements, international agreements, and non-terrorism laws." -- Jonathan Hall (KC), Independent Reviewer of Terrorism Legislation.
