Well, yes but it's not the Police doing the killing remember so what are you blaming them for....?
Where you around in the 1970s at the time of The Yorkshire Ripper murders and where you actually living in the Yorkshire area when the early murders were seen by the police and media as some form of divine retribution ?
High-ranking police officers making statements about "good girls" (their phrase NOT mine) and "women who choose to live on the seamy side of life" were the order of the day.
Very judgemental.
The police interviewed Peter Sutcliffe on many occassions yet failed to arrest him ....
A psychic even gave amazingly accurate details on the murderer ; ignored as "cranky".
A measure of incompetence is therefore self-evident ; I can allot blame .
Your second point (in red) seems nonsensical, are you suggesting that given the killer is targetting prostitutes (the 'bad girls') are you advocating that the police advise them to stay on the street to help ensure that these shop assistants, Doctors, Civil Servants (the 'Good girls') are safe; as if they couldn't be prostitutes either or do you consider them somehow more 'worthy' of protection? I don't think that's what you mean but if that's not what you're saying could you clarify?
