It happens more often then you might think. Just take the case of Sherman Austin for an example of countless others. He was essentially a political prisoner. Its one of the more publically known cases of the unconstitutionality of the PATRIOT Act, and how that act as well as warrentless wiretapping may be used directly against United States citizens. Its also a good example of how our government likes to bypass certain people's rights to due process and writ to habeas corupus under such unconstitutional "anti-terrorist" legislation. It also shows the effects of the unconstitutionality of Clinton's Antiterrorism and Effective Death Penalty Act. Look it up yourself, you wanted a name so there you have it.
