How do you prevent crime? While the ability to peer into criminals’ thoughts and predict bad behavior isn’t a reality just yet, there are a number of tried-and-true methods to deter theft and robbery. Among the most popular are placing valuables out of sight and ensuring your home or business always looks occupied, even when you’re away. Monitored alarm systems are also critical, and it’s common sense to make sure there’s always a source of light. But a new study from London School of Hygiene and Tropical Medicine in partnership with UCL has discovered that more light may not mean increased safety.
