Prison for protesting - climate change activists or criminals?

The long prison sentence given to Sydney climate protester Deanna 'Violet' Coco for blocking traffic on the Sydney Harbour bridge has surprised many, including her fellow protester Jay, who spent 42 days under house arrest. Are new laws suppressing fundamental human rights to protest, or a proportionate response to disruptive blockades?

Note: Since making the show, Violet Coco, has been released on bail, as from 13th December.
