The misuse of guns is a problem for lots of countries across the world. This week we look at projects trying to reduce deaths and injuries.

In the US we visit the company which says it has successfully developed the world’s first ‘smart gun’ which uses facial recognition and fingerprints to identify the gun owner - meaning only they can fire the gun. We also speak to a woman who’s convinced police in the UK to speak to the partners of those being issued gun licences.

And in Jamaica - where most murders involve firearms - we find out how hospital data is being used to reduce the number of attacks using guns - even in the country’s most troubled neighbourhoods.
