New 4 part documentary on Netflix which has frustratingly accurate footage of the police's disregard for the victims. It was their arrogance which blinkered their investigation for far too long before he was finally caught. Not by the extent of their police work, but by officers arresting him for a completely unrelated offence, which the bigwigs happily took the praise for. Although I've seen something very similar before, it's still a very worthy watch.
