@1stmonkey are your comprehension skills so poor I have to repeat myself?
It is entirely possible and has happened before that a force in such a situation has certain events (because there are known tensions) covered by other forces from around the country. I think the there's even been cases where this has crossed internal Uk country borders (eg a Scots force swapping with an English one)
It absolutely could and should have happened here.
the Met police are responsible for the Clapham area
While ordinarily that may be true, there are times when such a decision is inadvisable and this was one of them
Who else was supposed to police it?
Off the top of my head I would suggest due to proximity/logistics:
Cambridgeshire
Essex
Thames valley
Herts
Sussex...
you can't just draft police in from another region though ,its not just that simple I'm not saying it's simple. I'm saying it's possible - with the will to do so present
Sadly, women who buy into the patriarchy's world view are also the problem. They seem to resist the instinctive reality of their lives.
Agreed perfect example of cognitive dissonance
You don't draft in other police services to do your job just because it's difficult.
You do when you responsibly acknowledge that your presence is not helpful and even provoking. Which is why it's happened before
