Study Shows Video Surveillance Reduces Crime

But how trustworthy is that number?

Inside this note, IPVM examines the study published jointly by US/UK-based authors, discussing its finding that video surveillance reduces crime and pointing out limitations due in part to the age and geographic scope of the study data.
