It’s worth remembering that the police didn’t have the benefit of modern computer systems and DNA evidence. Police station floors were strengthened to bear the weight of the paper evidence collected and it would have been nigh on impossible with the resources they had for results to be cross-checked and properly analysed. Yes, huge mistakes were made, particularly the credence given to the Wearside Jack tape, which led directly to the evidence of some survivors being discounted as their attacker had a local accent. But many dedicated officers gave their all to this investigation, often to the detriment of their personal lives. Thousands of people were interviewed because of their frequenting certain areas, because of the cars they drove, the jobs they did, their physical descriptions. Many were picked up several times, including my DSIL. I was interviewed myself as I lived in the area and originated from Durham, so had relatives visiting who had what they thought was the accent they were looking for.
With the confidence of the young I never stopped living my life to the full, though we’d all be on the alert. We’d to crack on - I had a mile walk home from my bus stop after work and this was often in the dark, but the only time I ran from anyone was when I heard clanking behind me and turned to see a man following me wearing a workman’s belt with tools hanging from it. Then one of the victims was found in a back alley just a street away from where I’d lived a few years earlier as a student, in a ground floor bed sit with no window lock, also looking out onto a back alley.
No doubt about it, they were scary times.
