We see how thousands of repeat offenders – including burglars, robbers and thieves – are being fitted with electronic GPS tags, and in many cases their movements are being monitored 24/7. Probation officer Suzanne Bennett tells the programme that, in her experience, no-one wearing one of these tags has reoffended.

Also in this episode, West Midlands Police Sgt Tony Webb fears for his life when a man points what looks like a gun straight at him. But back-up quickly arrives, and body-worn video cameras capture the dramatic events, including the moment the man puts down his weapon and is detained. Footage like this can be vital evidence, and the latest bodycams can be set to be activated automatically, ensuring incidents like this are always recorded. Show less
