Is your children's school conducting drills to teach teachers and children how to defeat an intruder?

The recent shooting in Oregon has many thinking about how to prepare for a would be intruder. Some schools are conducting drill days where teachers and students learn how to react during a hostile intruder situation. A friend of mine who teaches at a middle school said her school has begun these types of drills and that she had employed her own method of securing the door to her classroom with a metal bar and had placed other items in front of the door. Here is a picture I found online of how the members of one classroom prepared to ward off would be hostile intruder. "They left the door unlocked (on purpose) and employed a $1 countermeasure that prevented" the would be hostile intruder from getting the door open. When the door was opened the intruder found this. Had the intruder gotten past this, the students had several gym balls ready to throw at him/her "to simulate heavier, more painful objects". "With just a little bit of instruction the teacher had prepared these students to win in a horrible situation." Have you talked with your children about how they could fortify their rooms, throw things at the intruder and or breaking a window to escape? I like the idea behind this, "Train them to WIN instead of huddling together in a room and hoping nothing bad happens!" What about using this same training method in other settings?
