4. Childhood school bullying

The majority of the school shootings have been caused by people who grew up being tortured by other people at school.
These children spend many years terrified. As this happens, their inner resentment grows. Years of enduring abuse by fellow students eventually causes many of the tortured children to snap.
Growing up in school, I knew plenty of kids who were tortured as kids for many years by fellow students.
In junior high, there was talk at the school dance of the bullied kids plotting to chain the auditorium doors shut and set the building on fire.
School bullying needs to be exposed to the public, solved and prevented.
