You see, it’s a short hop, skip and a jump from allowing government agents to lock large swaths of the population up in detention centers unless or until they can prove that they are not only legally in the country to empowering government agents to subject anyone—citizen and noncitizen alike—to similar treatment unless or until they can prove that they are in compliance with every statute and regulation on the books, and not guilty of having committed some crime or other.

It’s no longer a matter of if, but when.
