Mythbuster - Does crime prevented mean crime displaced?

Why implement anti-burglary interventions when, as a result, burglars will merely relocate their activities to another nearby area? It is sometimes believed that implementing prevention interventions, such as CCTV cameras, will simply cause offenders to shift their activities to different locations, change their methods or find new targets. Yet this is only one of the possible outcomes an intervention can bring about. In practice, crime displacement is often outweighed by two other outcomes: a ceasing of crime and the diffusion of crime prevention benefits.
