We don't remember and mourn all women's deaths at the hands of men.
We don't even hear about most of them.
This one interested the media as she was young good looking middle class etc
Then it was a copper.
It just was a thing that touched a nerve and got momentum at the time for a mix of reasons.
'...so the last 2 points mean there is no political advantage for certain groups in protesting her death.'
What does this mean? Yes the vigil itself got some iffy interest but in general women have had enough. The met are awful. I would have gone if I didn't have kids to look after. Would I have been looking for political advantage?
As for doubt it was to do with work. Why? I know someone who works in law enforcement who has been bombarded with stuff by a person they came into contact with, for more than 10 years. You're guessing? That that's how things work. That's not how things work especially when a man has decided to focus on a woman for whatever reason.
