A violent-intruder drill Monday in Greensburg was the result of about five years of preparation by the Westmoreland County Department of Public Safety and Westmoreland Casemanagement and Supports, Inc.

Public safety officials used the drill as a way to gauge the response to a situation at the agency’s offices at the Davis Center, while employees learned how to react in such an instance.
