The public was told to stay away from Shasta High School Thursday, as an alarming scenario was unfolding. Redding Police Department hosted a multi-agency active shooter training all day and into the night. Many officers with guns out were moving around the campus in tactical mode to reenact the situation with help from smoke machines, recorded gunfire and actors playing the parts of victims, but it was only a drill. The Shasta County Sheriff’s Office also had a training exercise, though it did not involve role playing. Sheriff’s officials were joined at the Office of Emergency Services Headquarters by CHP, Redding Police and other local agencies, along with private enterprises such as PG&E, to discuss proper responses and procedures in the event of a failure of Shasta Dam and the resulting massive flooding.
