I was there on the day and it was frightening.
The cops basically cordoned off the city and the rioters (and innocent bystanders like me) were caught in a trap and couldn't get out for hours. I saw cars being rolled and set alight, the crowd chased, caught and attacked a photographer in front of me. Shop windows smashed, looters, the works.
I blame Dave Dobbyn to this day. The guy's a tool of the first order. He was willfully working up the crowd and taunting the police.
