As I write this, it is two years to the day since four students were murdered by a classmate at Marysville-Pilchuck High School in Marysville, Washington. 15 years earlier, I was a junior at that school, looking around the campus on the morning of April 21, 1999. It was the day after the massacre at Columbine High School in Littleton, Colorado. School shootings were not as commonplace as they would become but I still remember feeling that if someone really wanted to commit such a horrific act on our campus, there would be little to stop them. Tragically, 15 years later that would turn out to be true.
