Text: “DNA test jailed innocent man for murder.” BBC news. https://www.bbc.com/news/science-environment-19412819
Extract from the article: “David Butler has every right to be cynical about the use of DNA evidence by the police. He spent eight months in prison, on remand, facing murder charges after his DNA was allegedly found on the victim… The DNA sample was only a partial match, of poor quality, and experts at the time said they could neither say that he was guilty nor rule him out. Nevertheless he remained in prison – despite other CCTV evidence allegedly placing Mr Butler in the area where the murder took place being disproved.”
The police in this case seemed to view DNA evidence as “indisputable” but that proved to be far from true.
