The first time Heather Martin experienced a lockdown drill, the traumatic memories from her past resurfaced.
As instructed, Martin locked the classroom door, switched off the lights and covered the windows.
As a student close to 20 years ago, Martin remembers that disaster planning seldom went beyond a common fire drill. They didn’t prepare for the possibility that a gunman could stroll onto campus and terrorize scores of children. A month before graduating from Columbine High School, Martin was in the choir room when tragedy struck. On April 20, 1999, two students conducted one of America’s deadliest mass school shootings, killing 13 people before taking their own lives.
