Whoever at the school called the police should be hit with charges of calling in a false report, or calling in a false alarm.
But lest it appear that this was an overreaction from the school, as the mother described it, this is actual protocol, decided upon at an earlier meeting between the police department, representatives from the county prosecutor's office and school officials at William P. Tatem Elementary School in Collingswood.
From what I’ve read elsewhere on the net about this story, the authorities at this school were calling the police several times a day, day after day, for stuff like this.
You could stop there and still be correct
