In just one week, a wave of violence left six students and a principal dead. All of them were gunned down - in schools. At a national conference this week, President Bush urged the nation to help stop school violence. Doctor Stephan Sroka, a local expert on school safety, attended that meeting. He'll tell us what really happened, and what should have. We'll talk about what can be done to make schools safer Friday morning on The Sound of Ideas.Dr. Stephen Sroka, President of Health Education Consultants and Adjunct Assistant Professor, School of Medicine, Division of Adolescent Health, Case Western Reserve University
