As I've said, it's a mixture of approaches targeting the most high-risk offenders, the people the police know about, the ones who they know are dealing, the ones they know are involved in leading the gangs, and using tough sentencing in those cases but also working with the community leaders to change attitudes within those communities about the use of violence.
Some of that can be through the use of public campaigns with posters telling people what the consequences are, saying: do you really want to end up your life in this way? Some of it is through the use of community forums with discussion about what people would prefer to do. A lot of it is in terms of implanting projects in the community using people who are often former gang members themselves, which is a very powerful way of helping to change the attitudes of young people.
