The facts around the failings of a succession of senior officers leading the Ripper case are well known. It was a farce of a situation that eventually overwhelmed them due to their obdurance, institutional promotions and inability to embrace modern thinking, endemic mysogyny based that and the contemporary societal times and thinking, and systemic failings that werent equipped to deal with a serial killer which the subsequent review and introduction of the HOLMES computer system was brought in for to counter the old card filing system upon which murder investigations were based. This isnt news. Would always invite people to read the definitive work on this, Michael Bilton's Wicked Beyond Belief. Or for those who dont have time or prefer TV, the Netflix documentary series the The Ripper is excellent and faithfully based upon it and his sources with footage that brings it to life
