Yeh, the poster should have also at least name checked the administrative detention system of CIA's Phoenix program in Vietnam, which seems like a reasonable test-bed for many of the recent and horrific systems and a kind of common ancestor to both of the US ICE agency and its cousins in the Levant.
Leaving that bit of history out certain seems like a missed point of history, and absent that your parent post's point might indeed seem a little reach-y.
