Ignoring victims of crime is not 'a mistake'.
Which crimes were ignored or not investigated? It took time for the police to link the crimes. Especially in an area where violent crime was common place
WY was/is a high crime area. PS was not the only man murdering, maiming or attacking women in the area at the time
I'm quite aware of West Yorkshire, it's where I spent the first years of my life and where I have visited relatives frequently.
My comments on the area are more for the benefit of everyone.
I watched documentary a few years ago, maybe 5 years ago, the senior officers being interviewed were still talking about 'innocent' victims.
The Ripper Files?
The programme I thought was balanced and yes it did show one former police officer, or was it a prosecutor, who made a poor remark but it also showed a number former police officers who had worked on the investigation who didn't and had worked hard on the case and who did sympathise with all the victims. It also showed former female detectives who had too.
Oh and they were offered the use of a computer.
Did they take up the offer? But how much use a computer of the time would have been is anyones guess. The paper data that would have had to be put into the system, a computer system with every limited primtive capacity, would have been vast, and very time consuming
