This sentence could land you in prison for life if they go ahead with "suspending" habeas corpus. Remember folks, if your detention cannot be challenged legally, it doesn't matter AT ALL whether your detention was legal. If you think they'll never come for you, you're forgetting that they'll rely on the volunteer army of MAGA "informers" who will turn you in for treason because you annoyed them by being kind to someone they were bullying or something completely trivial. Without habeas corpus, suspicion is sentencing.
I know first hand of an anti- DEI-ban protest that occurred on a college campus in a red state. I also know first hand that the Turning Point USA group chat had at least one individual, a student of that same university, threaten to call ICE on this university-approved peaceful protest, as they were upset at the noise.
No, the courts absolutely couldn't save you, that's exactly what suspension of habeas corpus means - habeas corpus means that if you're imprisoned, it can be challenged in the courts by you or someone else. If you lose habeas corpus, no one can challenge anyone's imprisonment legally. It removes the right to trial. Your right to a trial if you're imprisoned is called habeas corpus.
