Introduction

This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book concerns a theoretical analysis of the concepts of reintegration, radicalisation and de-radicalisation. It examines the policies that aim to deal effectively with suspected and convicted extremists both inside and outside the prison gates. The book also considers the involvement and possible roles of police officers in counselling and assisting former detainees. It also fills an important gap in the research on radicalisation and de-radicalisation of jihadist suspects. Since 11 September 2001 (or, more commonly, 9/11) the threat of jihadi terrorism has been high on the security agendas all over the world. In many countries an initial series of legal, intelligence, police and executive measures followed suit. The process of radicalisation, arrest, release and reintegration does not take place in front of the camera. Terrorist attacks, arrests and sometimes the initial and closing days of a trial easily garner wide public interest.
