It seems biker paranoia is alive and well in Tassie. If you get a chance have a look at this story, http://www.themercury.com.au/article/2010/01/15/121685_tasmania-news.html
If you read the comments you'll see it's the riders vs the non riders. It starts off as a story about a funeral ride where the riders didn't wear helmets, and turns into a bikie bashing spree. It seems the association laws apply here as every person who has every ridden "a bike that makes such a loud noise" must be a criminal. FFS!
Are they for real down there, can"t the cops get a real job?
