"The book is a well written, clearly structured, thoughtful and measured account of issues such as current state practice, judicial consideration and relevant international law...In essence Targeted Killing in International Lawis a book about balance and the desire for careful consideration before the application of policies involving the destruction of lives. Melzer deals with each of the legal issues involved in targeted killing with clarity and precision...Melzer's detailed examination is a large step forward in the development of a better understanding of the issues and particular pressure points that daily engage advisers, courts, international lawyers and politicians when trying to determine when the state is in the position to take lives."
--The Australian Yearbook of International Law, Volume 27
"Melzer's book makes a significant contribution to our understanding of hot targeted killing is regulated by international law. His sensible definition of the problem, his principled division of the analysis into law enforcement and hostilities paradigms, his provocative analysis of military necessity, and his coverage of often overlooked aspects, such as booby-traps, will no doubt influence future work on this issue."
--William Abresch, European Journal of International Law, 2009
"Mr Melzer's monograph is a very articulated and expert account of the legal framework governing targeted killings in both peacetime and during an armed conflict. It is recommended for those who want to expand their knowledge of the topic."
--Vincent Roobaert, Assistant Legal Adviser, NC3A
"Targeted Killing in International Law is a piece of solid scholarship which can only be recommended to scholars, practitioners, and students alike...it is a very methodically researched treatise which will become a useful work of reference on the topic. It is definitely a step towards finally settling the legal problems surrounding the question of targeted killing and will hopefully help to bring an end to the 'shadowy realm of half-legality and non-accountability.'"
