"So far this school year, major crime in schools is down 10 percent over last year’s record lows, but today’s troubling incidents make clear the importance of our obligation to make schools a safe environment for learning. I’m calling each of the families of the students who were stabbed, and we are working hand in hand with the police department, whose investigations have already resulted in a series of arrests. In the last eight years, major crime in our schools has been cut nearly in half, but any level of violence in our schools cannot be tolerated."
