In a comment on a previous thread, GeniusNZ opined that expatriate Iraqis fearing retribution against their relatives were simply being paranoid. Unfortunately, it seems he's wrong. Voting was disrupted at the Sydney polling station after a small riot broke out when Wahabi protestors were discovered to be photographing voters. The polling station was later closed for an hour due to a bomb scare.
If this had happened in an Australian federal or state election, there would be a very clear remedy available. But as this is an international election, conducted by the International Organization for Migration, the best they can do is apply laws against stalking, intimidation and assault. Hopefully, that will be enough.
