It's only violence against women, caught on camera, with the perpetrators clearly identifiable, especially if their names are written down in party conference documents.
So you can't expect anything to be done when the victims are women. Even women on this site were victim blaming, asking 'what she did she do before [recording started] to deserve that'.
I very much doubt anyone will ever be prosecuted for this, a clear and recorded assault, and it is horrifying.
