Fighting Crime (Public Engagement)

I am slightly worried about advertising because evidence from the United States is mixed. For example, the ““Scared Straight”” programme, which showed young people the consequences of their actions, appeared to lead to an increase in crime. It appears to make a genuine difference when the person at risk is emotionally engaged with the consequences of a potential action. Such consequences do not necessarily emerge from advertising. What evidence can the Minister give the House to show that generalised advertising programmes, which do not necessarily have the emotional impact of a restorative justice programme, will lead to a reduction in crime?
