Final answer:
Increasing security personnel is identified as a successful response to prevent school vandalism, with the broader context indicating that deterrence strategies and broader social interventions are also effective in preventing crime.
Step-by-step explanation:
According to the text, one of the responses to prevent school vandalism that has been successful is increasing security personnel. This measure is considered a form of deterrence approach, which seeks to prevent crime by raising the costs or the probability of getting caught. For example, installing more lighting or using body cameras for police officers, are deterrence strategies that have been found to reduce crime and police violence respectively. Similarly, other interventions such as improving education, providing economic opportunities, and de-concentrating poverty have also been identified as effective means to prevent crime and could be extrapolated to preventing vandalism in schools.
