A Safe School

Last night I watched the NHK special about the school where several students were stabbed to death by a man. What I didn't like about the program is that it focused only on the school--how teachers have been struggling to create a safe learning environment. But the problem is that what happens inside the school is not unrelated to what happens outside the school. Can any school be improved without cooperation with families and neighbors? (It can, but not as effectively as otherwise.) I hope more parents in Japan will grow up to become partners of schools instead of totally depending on them.
