This book argues that 'ethics' and 'security' are interconnected and that they also reinforce each other. It provides a peer-reviewed, state-of-the-art analysis of this interrelationship. Classical examples of organizations charged with security tasks - such as the police and the army - are among the subjects of research. Additionally, the private security sector is examined. The book deals with moral wrongs, such as: corruption, the disproportionate use of violence, the fabrication of evidence, or the discriminate distribution of safety. In addition, it also highlights the bright side of the ethics debate in the context of integrity, international cooperation, and human rights, thus providing a balanced assessment of the issues involved.
