Adding to the "another reason why governments should be allowed to filter Internet - not even with a 'think of the children' approach": Australian government retains Julian Assange's passport and returns it after saying it will be cancelled. Julian is the founder of Wikileaks.

Last year Wikileaks posted the list of blocked websites in Australia. Obviously the Australian government thinks that filtering is not enough, so decided to limit Julian's right to travel. This year Wikileaks posted a video of a US force engaging with a group that included a journalist and photographer. They also show documents from other sources.
