(CNN) Vigilant community members attuned to warning signs from potential shooters were instrumental in thwarting many school attacks between 2006 and 2018, according to a report from the US Secret Service that gives new insight into how attention to concerning behavior can stave off mass shootings beyond schools. In every case of a thwarted attack, a member of the community -- such as a fellow student, school staff member or a parent -- contributed to stopping the attack. The report highlighted a startling incident in which a mother discovered kitchen knives were missing and contacted her son's school. When the child was removed from class, knives, a handgun and more than 460 rounds of ammunition were discovered in the child's backpack. He was just 11 years old.
