That’s also before accounting for the various ground scientists who would rapidly become aware through the private channels. Someone appearing on the ISS would leak beyond containment before anyone could think to cut phone communications, let alone implement it.

Compared to telefragging someone on live tv? Also, on the balance, the media coverage would likely help knock loose some more funding for NASA, if only to try and figure out what the f*** happened.

Scientists are not good at keeping secrets, particularly not of this level. Also, the ISS is remarkably public. It would be obvious they were hiding something, at the very least.

Would I expect to spend some time “volunteering” in a research lab, more than likely. I doubt it would get to dissection level. The risk/cost would be low enough that I would take it.

The International Space Station. The sheer confusion value would be amazing, particularly if I stayed quiet about how it happened (“I went to bed, then woke up floating here. I’ve no clue how it happened”).

I would get to cause a major incident of complete chaos, with little to no harm. I would get to experience space and weightlessness. I would also get a near guaranteed lift home (eventually). There’s also almost no way it could be kept quiet, so I get to be a minor celebrity for a while.

Many places make it illegal to allow police to intercede. In most places, the police can intervene if they believe a crime is about to be committed.

There is a huge line between someone who is terminally ill, and wants to die on their own terms, and someone having a mental health crisis. The first should be legal, but still needs support and checking, the 2nd need immediate help.
