While still considered unusual in the Australian context, most of the arguments about masking up at public protests are well-rehearsed. Perhaps the most important point to consider is that, prior to the emergence of the internet, the documentation of protest activity, including the identification of those involved, was largely a matter for the state and media. This is no longer the case. With the advent of social media, what happens at such events is now the subject of intense scrutiny by participants and observers, and there is an ongoing battle to shape the narrative surrounding them.
