While this short video about an almost school shooter is difficult to watch, we must remember that many people are bullied in school without entertaining thoughts of shooting classmates.
Similarly, making and breaking relationships goes along with high school culture, yet most people who experience a break-up do not think of harming others.
Anxiety and depression are also common, especially in adolescence, without young people committing violence in real life.
This means there is no one way to determine who will act on their feelings and become a school shooter.
However, one solution school administrators have is to conduct risk assessments—help train educators on ways to detect warning signs and take them seriously.
