Trevor Timm, The Guardian columnist writes about the truth about the miscarriages of justice and how frequent they actually are. He specifically writes about a case described in Netflix’s original documentary episodes called ‘Making a Murderer’, which I am personally watching. Episodes and the article describe a case of Steve Avery, who spent 18 years in prison for a crime he did not commit, and, shortly after his release, got convicted again, for murder under shady circumstances. This is an excellent article for anyone willing to find out more about the Avery case and errors leading to miscarriages of justice.
