A standard drywall wall (above) and even double sided steel doors provide ZERO protection from an active shooter!
Twenty years of business as usual by School adminstrators are over. If you are a parent and your child attends a school that requires them to "shelter" behind standard doors and drywall walls during an active shooter incident, you need to insist that your School's administrators view this video and demand that they take school security seriously and insist that they stop telling children to "shelter" behind doors and walls that provide zero shelter during active shooter incidents. Contact your Local, State and Federal representatives and demand that they require schools to provide adequate ballistic shelter and security door blocks for every classroom during active shooter lockdowns. This is a deadly serious matter and there is absolutely no excuse for anyone engaging in "business as usual".
