I never understand why this happens. You like to believe you send your kids off to school, and they are relatively safe. Our elementary is locked down. You can only get into the front hallway, then you have to buzzed in by the office. When I was little, I remember a guy with a gun in our school. The classroom doors were all closed and locked, and the police showed up and took him away. Never would it have occured to me that he was going to shoot anyone. Now that's the first thought that comes to peoples minds.
Makes me sad...
