Ismael ‘El Mayo’ Zambada García, the senior leader of the organisation known as the Sinaloa cartel, was arrested on 25 July, together with his godson Joaquín Guzmán López – one of ‘El Chapo’ Guzmán’s sons. The best Mexican coverage was informed by long experience, scepticism and sober realism. It was hard to believe the authorities had finally captured the man who never left the Sierra Madre. Across the border in the US, where the arrest took place, more than a few journalists appear to have cut their sociological teeth on the Netflix series Narcos: Mexico.
