Whatever the actual facts of the situation, which will be hidden behind the usual multiple layers of rainbowed tat from most of the media, the optics are very helpful, picture paints a thousand words etc and sticks in the memory.
Large crowd of mostly blokes shouting threats and filth with police looking the other way and pretending not to be there. Woman not looking like an escaped member of the local youth drama club and not shouting obscenities or threats or waving bits of wood or her genitals, walking quietly as she is led away by several police. Who apparently felt much safer to feel her collar, and who can blame them.
