A video that appears to show armed policemen fleeing a scene seconds before a murder takes place has gone viral.
In the mobile phone footage the officers seemingly ignore bystanders who want them to intervene to prevent the killing. The video, reportedly filmed in the Mexican state of Sinaloa, has provoked a debate about the role Mexican police play in the safety of the country's population.
