Edit: derp, it’s fucking ICE that has no records, so my idea makes no sense. Who knows with that fucking circus.
I can think of a third possible option: some are hiding or have fled the country. If I was illegally detained, put into a concentration camp, then released, I’d fucking disappear posthaste.
Not sure of the likelihood, but one can hope.
It depends on the speed and size of the centrifuge, the mass of the load, and the magnitude of the imbalance. Someone else mentioned an ultracentrifuge, typically a large, washing-machine-like device that can spin larger loads at high velocity. The amount of energy released if they become significantly unbalanced is pretty huge: they have a containment layer, but some could kill you if the load got through and hit you.
On the flip side, I may have intentionally ran unbalanced microcentrifuges a few (many, it was many) times as a grad student because I was too tired and lazy to make a counterweight. I just held it down with fairly firm pressure and it was fine. That’s not very good for its bearings, though. Sorry lab manager!
