Can police stamp out violence in South Africa’s taverns?

When Alan visited Johannesburg in July, the city was reeling after a mass shooting at tavern in Soweto. Sixteen people were killed by gunmen while socialising with their friends. It a spotlight on increasing violence at drinking spots across the country. That month 25 people died in such incidents. Last week, five people appeared in court in relation to the shooting in Soweto. But the people Alan spoke to at a tavern nearby said they had little confidence that the police could keep them safe. Is that the case?
