"Hell, the UK is the only place I ever heard of where those wrongfully imprisoned are then forced to reimburse the government for the cost of their imprisonment."
For some years now, if you enter Australia as an asylum-seeker - which is not illegal - you are put in detention camps - sometimes for years.
When/if you are deported you are given a bill for your detention. My nephew-in-law received such a bill for around $AUS250,000. Fortunately it looks like the newish Rudd Government (with support from some of the opposition) is going to reverse this.
But I think my point stands - people are locked up in Australia for years having committed no crime and are given a bill for their 'accommodation' when they leave. ...oh and Australian's can can detained for ages without trial with no one knowing why or being able to report on it... ...only in America? I wish!
