The George Carlin bit I posted might seem flippant but he illustrates the point so nicely.

In the USA (and Canada) people were stripped of their rights and marched off to concentration camps for the crime of being born to people of the wrong race. That is what your rights are worth; they exist at the pleasure of the government.

The latest manifestation might be being labelled as an "Enemy Combatant" or "Terrorist". The government can make any distinction it chooses really; rights are a fiction that exist only so long as it is useful and disappear when they get in the way.
