Dealing with this contentious and provocative topic, this book explores all aspects of the law in relation to covert investigation, paying particular attention to surveillance law and the admissibility of evidence. The recent growth of interest in surveillance, the interception of communications and the government's 'War on Terror' are key issues that have provoked challenging new debates in this area.

Covert investigation allows evidence to be gathered without the co-operation and awareness of those being investigated. Methods such as the interception of communications, including email, surveillance and the use of informants are commonplace but invariably throw up important issues concerning ethics, human rights, privacy and permissibility of evidence. The recent growths in legislation and codes of practice regulating this investigative technique have done little to quell the controversy surrounding its methodology.

This timely work is an invaluable resource for police investigators, lawyers and researchers in the fields of criminal justice and police powers.
