It is hard to believe that the Columbine High School shooting was 19 years ago. The actions of the two suburban Colorado high school seniors who went on a shooting spree killing 13 people and wounding over 20 others before taking their own lives should have been a clarion call for common sense gun control. Sadly, the nation would hear the same refrain in 2012 in the bucolic Connecticut town of Newtown at the Sandy Hook Elementary School massacre, where the 20-year-old gunman shot and killed 20 six- and seven-year-old children and six adult staff members before killing himself.
