Despite being witnessed by dozens of people in the neighbourhood and part of it captured on video Greek courts were unable to convict police officer, Epameintas Korkoneas who on December 6th shot and killed 15 year old Alexis Grigoropoulos in Exarchia, Athens. As 18 months had elapsed since the officer's arrest the court was obliged to set him free.
The death sparked off riots that lasted nearly a month and cost the country billions in damages as outraged Greeks repeatedly clashed with police across the country and produced the worst civil unrest in a generation. The ferocity of the response was, in part fuelled by the conviction that the police officer would not be punished.
It seems that the officer has been released but the trial is set to continue. The 18 month limit was how long somebody could be held pre-trial before the courts were obliged to release them. Thanks to blogger Lollipop for putting me right on this.
