Climate Protesters “Cookers" Blockade Australia

A small fringe group of climate activists are blockading Sydney for a week to save the planet! Are the police being heavy handed in responding to their disruptive protests or do they have a right to be a public nuisance?

Supporters of the Blockade Australia protest group have in the past disparaged other legitimate protesters in Australia as "cookers" that should be ignored and shutdown by police, but now the shoe is on the other foot, are these the real "cookers" that should be stopped?
