Officials from the City of Danbury, the schools and West Conn are updating their emergency communication protocols.  Following the recent lockdown at some public schools because of an unfounded report of a gunman on the university's west side campus, some gaps were discovered.  The Newstimes reports that in the future, a police officer will be dispatched to Superintendent Sal Pascarella's office to keep district staff in immediate contact with police on the scene of an emergency situation.  A plan is being developed for buses.  Due to the timing of the lockdowns, around dismissal time, there were questions of what to do if some students were already on buses.
