Active Shooter training is not required, it just makes good sense. "Run. Hide. Fight.®" is one of the best training tools to use, especially when you have not had extensive active shooter training.

Failure to teach something because people might become afraid has caused lawsuits against businesses everywhere when something goes wrong. Everyone needs to know simple things they can do in an active shooter situation.
