Glenn D. Walters received his Ph.D. at Texas Tech University in 1982 with a concentration in Counseling Psychology and a minor in Neuroscience. He is employed full-time as a psychologist in a correctional setting while also teaching courses, both graduate and undergraduate, as an Adjunct Professor at The Pennsylvania State University, Schuylkill, and Lehigh University. In addition to forensic psychology, he teaches abnormal psychology, psychological assessment, and developmental psychology. He has written two other books with SAGE: Drugs & Crime in Lifestyle Perspective (1994) and The Criminal Lifestyle: Patterns of Serious Criminal Conduct (1990). The present book is an outgrowth of the author's experiences teaching criminology and forensic psychology and the realization that crime is better understood once students appreciate the context of criminal development and desistance.
