South Africa marks 11 years since the Marikana Massacre happened. On 16 August 2012, the South African Police Service opened fire on a crowd of striking mine workers at Marikana, in the North West Province.  The police killed 34 mineworkers and left 78 seriously injured. 

Is there is a political will to prosecute all those police who gunned down the 34 miners?
