The booklet emphasizes the importance of taking action when early warning signals indicate the need to prevent the development of more serious problems. Warning signs include abandoned autos, loitering, vacant homes, graffiti, or a rash of break-ins. Upon identifying warning signs, the first step is to find out what is already being done by various groups to address neighborhood problems. If there is no group that is focusing on crime prevention, concerned citizens should start one. This booklet describes how to organize and conduct a first meeting of neighbors interested in preventing crime in the neighborhood. Suggestions are offered for how to organize to get results. Guidelines for conducting activities include keeping it simple, inviting everyone to participate, following through on group decisions, starting with "small" successes, and showing appreciation for work done by group members. Other suggestions are to build leaders, be flexible, build links, keep in touch often, and assess progress. Other sections of the booklet focus on overcoming reluctance and fear that inhibits participation in neighborhood crime-prevention activities, the development of key partnerships for crime prevention, and resources for getting the job done.
