This means that we need effective and efficient lighting. Visibility is the goal. We want to be able to see, not just have the criminal be able to see. This goal exists for us at home, on the streets, in parking lots, at work, wherever. Good lighting can be a help, poor lighting always compromises safety.
Most crime actually occurs during the day, or inside buildings.
However, we want the feeling and the reality of being safe outside at night. That does not mean putting in the brightest light we can find, blinding everyone in the area, creating light trespass and lighting up the sky. Lighting in itself does not insure safety. We don't think so. Quality lighting rather than poor lighting is essential for any real security.
