From petty street crime to gangland murder, `Criminals: Caught on Camera' reveals shocking footage of actual crimes in the UK that are recorded on closed-circuit TV. Journalist Nick Wallis teams with over twenty different police forces in Britain to show how CCTV and technological advances are filming a wide range of criminal activity and leading to the apprehension of those responsible. The programme also explores the devious tactics of pickpockets, shoplifters and con artists, and looks at how camera technology has replaced some traditional policing methods.
