To the OP, the terminology is unfortunate in the post, since it immediately summons forth one memories of the worst humanitarian disaster in recorded history.
But, the parallels with current events in the US are unmistakable. It's hardly a secret that "all the president's men" are in process of exponentially enlarging their ability to crush dissent, and do their best to imitate the horrors of the previous century.
Of secondary interest is that these paramilitary dullards supposedly "need" places to live. They don't. Ice agents live in their own homes. When a "unit" of these "icicles" is sent to X location to perform their indignities, there is often a "unit" of ice people in the area the agents work from. Think of these people as an adjunct National Guard type of structure.
Thus, the building of (potential) concentration camps is only tangentially related to where extant ice facilities - at least at present - are located.
