So is nonaggressive behavior. A school curriculum including nonaggressive conflict resolution and problem solving could lower the level of violence, but that effect would be multiplied many times were the media, community leaders, and high-profile role models to join forces with educators in teaching that nonviolence is a better way. Aggression begets aggression, particularly when it is successful in obtaining desired ends and when it has become well practiced. Aggression often escalates from relatively minor belligerence to appalling acts of violence, and nonviolent consequences are more effective when applied early in the sequence. Restrict access to the instruments of aggression.
Aggressors use the most efficient tools available to damage their targets.
True, some will aggress with whatever tools are available. The more important truth is that having more efficient weapons enables aggressors to accomplish violent ends with less immediate risk to themselves and to escalate the level of violence easily. Restrain and reform public displays of aggression. The behavior one observes affects one's own thinking and overt behavior. Much of the fare marketed by the entertainment industry is saturated with aggressive acts, desensitizes observers to aggression and its consequences, and disinhibits expressions of aggression.
