On 4th March we heard from former gang member Jay about why he’d never leave the house without carrying a knife.

Jay has since been asked to make a Radio 4 documentary investigating the solutions to knife crime.

For the programme he met a trauma surgeon, a police commander and a local mayor. He also had a long conversation with a man called Callum, who is from Glasgow. Glasgow used to be the murder capital of Europe, but now that’s changed and the city’s seen as a model for how to stop violence. Callum got caught up in a lot of violence and was stabbed nine times in one attack.

This episode is the conversation the two of them had for Jay’s documentary, in which Jay asked Callum about how he moved away from violence.

You can find Jay’s documentary “My Name Is... Jay” on BBC Sounds. It was produced by Gaetan Portal.
