Curfews are most effective when used a short-term aid to other policing measures.  Other schemes aimed at reducing youth crime are highly effective but work best in conjunction with curfews. As the National Crime Prevention Council states: ‘A curfew alone won’t stop crime. More preventive measures, including recreational activities and job opportunities, are needed to reach out to young people and keep them from committing crimes.’ 1 In areas with a whole culture of lawlessness a curfew takes the basically law-abiding majority off the streets, allowing the police to engage with the most difficult element. Curfews are a tool in the struggle to improve lives in run-down areas; they often used for relatively short periods of a few weeks or months in order to bring a situation under control so that other measures can be put in place and given a chance to work.
