Guardian Australia understands the video relates to legal proceedings from a protester who was charged with assaulting police. They were one of three protesters who on Friday had the charges against them dropped.

Police have now withdrawn charges against four of the 30 protesters charged in the wake of the protest. The three protesters who had their charges withdrawn on Friday were scheduled to face a joint hearing alongside 22 others in July 2027.

A petition launched in June by the NSW Council for Civil Liberties calling for the charges against all the anti-Herzog protesters to be dropped has almost 3,000 signatures.

The petition is an open letter. If you wish to sign it, details are in the comments.
