Some New York City schools have installed metal detectors to prevent youngsters from bringing weapons inside their school and school safety officers with powers of arrest, if needed, to keep order in schools. In addition, schools are conducting conflict resolution and anger management sessions, sometimes involving students' parents, to prevent small incidents from escalating into serious and perhaps violent actions. Good relationships between school principals and precinct commanders are also important to keeping the peace in neighborhoods. Mr. Yeldell emphasizes the role of parents, who, by means of something as simple as reading with their kids, can make a difference in youngsters' school careers. Youngsters who fall behind in school because of reading problems are much more likely to get in trouble and to cause trouble.
