I dont in any way want to imply I dont think what this report has revealed isn't horrifying, but ...
As other have said this have been known for years / decades.
The problem is that those who usually try and raise the issue have no status in society, so if you are a women, in you are a member of a BME community, if you are Lesbian or Gay, society does not listen. Because those in positions of influence, ie MPs, newspapers are exactly the same.
The Metropolitan Police are a reflection of our society, or rather male attitudes in society. Wherever there is a male dominated community, eg different religions, the armed forces, schools, people's own homes, men will behave as man feel entitled to behave knowing that because they are an enclosed group they can get away with it.
That is our problem. ie given the opportunity men will exploit their positions of power, and the few exceptions will decide they cant stay.
I don't know enough about the management structures, but suspect it is too big, but even if broken into smaller forces, I dont see how you can get away with the underlying problem. Men in groups of men, are a danger.
Added to which giving a report to Louise Casey is a death knell on anything being done.
You would think she would be too embarrassed to take on yet another investigation as none she has ever done has achieved anything. If she had any intergrity she would have said dont ask me to do another report until you can show me you will act of them. But still she's got her title and her fees.
That is what we need to know, not some litany of faults, but how do we achieve change when those who need to change are men, and that those who have the power to enforce change are men.
