As the emergency response system moves into action, Police, Fire, Rescue and Medical vehicles converge on the school. The Principal is trying to maintain control over the students while insuring that they are moved from harm's way. The office is vacated, as every administrator is involved in the crisis. Phones are ringing with no one to answer them. The Police are looking for someone to tell them exactly where the emergency is but office personnel are no where in sight.
News reporters start stopping students and teachers and asking for information.
Eventually, the Police have enough officers on site to enforce traffic control and they start blocking roads to keep parents, news media and rubber-neckers out. However, they offer no information because they do not know yet themselves. Parents start to panic as they are stopped short of school, told nothing and are away from their phones. There are Police and other emergency vehicles everywhere. One distraught student told me she thinks there is a bomb.
