This anthology provides insights into processes of violent extremism, both locally and globally, questioning how and why it arises and what can be done about it. The book will be relevant for policy makers, post-graduates and researchers in the social and political sciences, religious studies, law, psychology, medicine and education, as well as practitioners in direct contact with targeted individuals or vulnerable groups. The anthology contributes models, analyses and practical tools helpful for first-liners who are well placed to both see and prevent incipient extremism and to rehabilitate: to aid those who have been extremists in returning to society and finding a life worth living. In addition to chapters focusing on work in Norway, Denmark and Sweden, there are contributions from North America, Africa, Australia, the Middle East and Europe.
