Following up on yesterday's front-page story about a decline in Baltimore's violent-crime rate, the Midday show today looks at the research behind police-and-probation strategies to identify the most potentially violent offenders in city neighborhoods. The conversation is with Richard Berk, a professor of criminology and statistics at Penn, whose research into predicting criminal behavior has influenced -- and sharpened -- the state of Maryland's approach to offenders who are on probation. July marks one year since the Division of Parole and Probation adopted a new model of supervising released offenders, based in part on Berk's work. We'll be talking to Berk at noon, then after NPR news at 1, a status report on the state's efforts with Patrick McGee, director of Parole and Probation for the Department of Public Safety and Correctional Services. Then more on criminal behavior from Stanton Samenow, a clinical research psychologist and author of Inside the Criminal Mind.
