They Already did it Once

An American Civil Liberties Union lawsuit is challenging the federal government’s practice of mandatory incarceration for immigration detainees. The ACLU claims the government unnecessarily incarcerates deportation candidates even if they are documented citizens and pose no flight risk or threat.
 

That's right...immigration detainees are not a flight risk. *cough*   Dumb doesn't begin to describe this fiction.  Someone please change the sign to American Criminal Liberties Union.
