The National Center for Victims of Crime in the U.S.A. recently reported annual figures showing 103,845 American children were sexually abused, while in the same year there was a 20 percent increase in all rape incidents and a 33 percent increase in sexual assaults. Incarceration and therapy have not reduced the rates, points out this author. The rate of incarceration has increased, but incidence of sex crimes is not waning. Dobbert warns we must all play a vital role to reduce such crimes, by prevention. The seasoned forensic examiner enables us to see life through the sexual predator's eyes, to understand the motives and intentions of people with abnormal and uncontrollable desires. He argues we can create a safer world by removing the opportunity for such people to act on their ideas. The author clearly explains disorders from exhibitionism to paedophilia, and presents scenes that illustrate precursor behaviours shown by people preparing to act on such disordered thinking. Also illustrated are stalking patterns common to mentally ill people who commit sexual assaults or lust murders.
