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.
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.
