“Active shooter” tech demonstrated at Mass. school
In the live demonstration, the “gunman” entered the school armed with an assault rifle, opening fire with dummy rounds first in the school library then rampaging through hallways and classrooms.
But he had only a few minutes to wreak havoc.
Smoke alarm-sized sensors installed in classrooms, hallways and other points throughout the building were activated by the sounds of gunfire, and police officers immediately were able to track his movements and quickly subdue him.
Nearly 100 people, including U.S. Rep. Nikki Tsongas and regional law enforcement officers, gathered in the school to view the demonstration of what the school district bills as the first such system operating in a public school in the U.S.
