As a former teacher, I can tell you our school had lockdown drills for years. I have not heard that this school did so, and I find it strange that kids came running from the school, which is not what is expected since they could have run into the intruder. Kids are to take shelter. As to the courageous young man who was killed confronting he killer, although he is a hero, this, too, would have been a no no. I just do not think the school had a plan - and the location is ten miles from Columbine.
