Huge police presence made G20 protesters in Brisbane feel violence was justified

The 2014 G20 meeting in Brisbane had one of the largest peacetime mobilisations of police in Australian history, which protesters at the event perceived as a threat and justification for violence, say Australian authors. The team used a special survey to gather data on the protester's feelings around the summit, and suggest that the overwhelming police presence made the attendees feel threatened, and lead them to consider violence as being morally justifiable.
