Cherry Hill Mayor Chuck Cahn said between seven and 10 armed officers would be deployed to patrol the district's 19 schools and would remain there until at least the end of the school year on June 19. "Our schools are safe, but our goal is to make our schools safer, and not just with the presence of police officers, but with a multifaceted approach," he said. The district has about 11,300 students in grades K-12.
