18. In May 2002, the Secret Service published a report that examined 37 U.S. school
shootings. They had the following findings:
• Incidents of targeted violence at school rarely were sudden, impulsive acts.
• Prior to most incidents, other people knew about the attacker’s idea and/or
plan to attack.
• Most attackers did not threaten their targets directly prior to advancing the
attack.
• There is no accurate or useful quot;profilequot; of students who engaged in targeted
school violence.
• Most attackers engaged in some behavior prior to the incident that caused
others concern or indicated a need for help.
• Most attackers had difficulty coping with significant losses or personal
failures. Moreover, many had considered or attempted suicide.
• Many attackers felt bullied, persecuted or injured by others prior to the
attack.
• Most attackers had access to and had used weapons prior to the attack.
• In many cases, other students were involved in some capacity.
• Despite prompt law enforcement responses, most shooting incidents were
stopped by means other than law enforcement intervention.
