Qu: What do Australian police have to do with an American made film?
Answer: They are valid targets
Answer: Because protests have about as much to do with Mohammed as the deaths of a few protests in Libya & Syria have to do with the revolutions
over there. I.e. it the U.S film is simply acting as a rallying point every extremist muslim, can agree is worth turning up to protest about.
In other words the Australian protests say more about how the regime (in the form of a cross party consensus between Australia's party's) have let
in too many people who hate Australian politics, and Australians, and those who help prevent Australia becoming a tribal, anarchistic society like
where they come from (i.e. Australia's police, and employees generally).
