This book is the result of the cooperation of nineteen experts (magistrates, doctors, psychologists and tutors from various parts of Italy as well as the Communications Police Services) tackling paedophilia from three points of view: the juridical, the psychological, and from the viewpoint of the paedophile himself. This is one of the most original books ever published in Italy or abroad. It is important to also know the psychiatric profile of the paedophile in order to be able to treat this person and thus prevent any further consequence. The book also contains chapters dealing with the clergy and paedophilia and specific assessment methods by the criminal, civil and juvenile Courts. Particular attention is paid to indicators of abuse, diagnostics problems, and the possibility of error. Magistrates, psychologists, the Forces of law and Order, social workers, teachers and parents now have a technical, practical instrument available that is immediately useful in intervening effectively whether in an emergency situation or in daily life.
