Sorry haven't had time to read the whole thread so this may have already been said. And I dont say this to defend the police who have about as much empathy as a lump of granite.
But it has become evident from facebook that not only the SWP but Sisters Uncut were organising to attend this event. Both these groups have a parasitic practice of turning up at events with an agenda of engineering confrontation. (My local event not only had SWP but Global Women's Strike)
So why was it that earlier in the day a large number of predominantly women were able to attend in an unorganised way and not turn it into a violent confrontation?
These piggy back politicos never organise their own event to demonstate against the police, they just wait for some to organise a march or whatever and then they arrive to create confrontation.
I am sure the police over reacted, and used unecessary force. But given the smug posts being swopped about how these self styled warriors are portraying the event as an example of the police state that they bravely confronted, it seems that at least part of the trouble had little or nothing to do with women demonstrating against male violence or holding a respectful vigil for a woman kidnapped and murdered.

Her family who have asked for her name and image not to be used must be even more distraught than they were already as their daughter just becomes a prop in the usual photo op politics of the SWP and Sisters Uncut.
