Examples of successful solutions need to be brought to the attention of architects and educators. Not so much security from mad bombers, as in the Oklahoma City Federal Building, but security from the common robberies and assaults and occasional murders which occur in schools. Size is also a factor here. Smaller schools, where the faculty and administrators recognize the students from their faces and by their names, can more easily police themselves. Larger schools tend to hire professional guards to do the job.
Control is easier if teachers and administrators and students actually know each other.
School crime is not just a big city problem. In Texas the rate of school crime is higher in the mid-size suburban school districts than in the major cities. Schools need to develop systems to make sure they don't become cradles of violence and criminal activity. Young people constitute the largest group of victims of crime in America, and a lot of that crime takes place in school. Another recent Congressional Budget Office study reports that the majority of our existing schools cannot make use of new communications technologies.
