It's said that rights to protest are not specified in NSW. But one right is defined:
'In NSW, police can arrest you without a warrant if they suspect on reasonable grounds you committed an offence and it is necessary to stop, identify, or secure you (LEPRA 2002). Officers must state you are under arrest, identify themselves, caution you, and can use reasonable force.'

Police have evidently grossly failed that process at Town Hall. Was it Minns or the Commissioner who dictated the change?  Are they thinking they are copying Trump's ICE agents?  In any case, civil order and cohesion are damaged when police are uncivil and everyone then loses.

They just didn't hear the copers saying "You're under arrest, Mo!  Now get up off the footpath!"

No speak-a da English? 

Worldwide the idea is growing that mass immigration of Muslims was a mistake that needs to be reversed.
