I live in a neighborhood where package theft has become almost routine, so I've started researching whether security cameras actually stop criminals or just displace them to the next block. Some studies, like one from Rutgers University, suggest cameras reduce crime in targeted areas, but the overall effect on community safety feels murkier when you factor in privacy concerns. What's your take—are surveillance systems a necessary tool for public safety, or do they create a false sense of security without addressing root causes?
