The Huffington Post has reported on a video showing a man sexually harassing a woman and then getting beat up by her: http://m.huffpost.com/au/entry/9792076
It looks fake. For example the harasser tries to grab her breast by reaching over her shoulder rather than reaching around her, which doesn't seem practical, and it seems strange for an incident to have been noticed by the owner of the closed circuit TV footage (not to mention being leaked to the internet, and also reaching English-language media in a couple of days), unless one of the two reported the incident.
Is this video genuine, or is it staged?
