One week after a shooter armed with military-style weapons entered the Covenant School and murdered three children and three adults, more than 7,000 Nashville students staged a walkout to demand gun reform. It was a sight to behold: Vanderbilt University students marching down one street, Belmont University students marching down another, all of them joining a large crowd of high school and college students from around town. They are determined and it is these young people who will get gun legislation passed. We adults failed them.
