Yes and no. Not literally, but perhaps figuratively to a lighter degree but on a public scale.
There already have been detainments and excessive harsh treatment suspected terrorists without Constitutional due process normally afforded citizens, since many of these people were not US citizens or were already assumed to be enemy combatants against the state.
From complaints against Gitmo to a student in Colorado who was jailed for failing to meet the requirement that foreign students enroll in a minimum number of classes.
This has already been happening on a MILD level. Whole Mosques were targeted in Tennessee POLITICALLY by candidates competing for the far right Conservative votes.
Not necessarily detained in camps, but bullied and stifled by political and legal abuses,
using those venues as WEAPONS.
And the whole issue of the Patriot Act and the NSA spying on Americans
is more on an ABSTRACT level.
Targeting political opponents by abusing the IRS; selectively abusing the Judicial branch to push for or against certain political agenda as constitutional or not constitutional is another way to handicap political opposition as enemies, even if you are not jailing them physically.
