This booklet examines and evaluates several programs to educate juveniles about the dangers involved in carrying weapons and to provide nonviolent routes to developing self-esteem and personal responsibility. The booklet is based on the experience of the Vera Institute and its partners in planning and testing a weapons education program in Brooklyn (New York) in 1996-97. It draws lessons from three programs in Detroit (Michigan), Indianapolis (Indiana), and the District of Columbia. Among the subjects discussed are: (1) defining the target population; (2) deciding when to intervene; (3) facing resistance; (4) making the program voluntary or mandatory; (5) developing program content and facilities; and (6) determining what to expect from a low-intensity, low-cost intervention.
