To the best of my knowledge, doctors don't experiment on patients without their consent, drill burr holes without circulation, or generally just do anything they want without fear of prosecution (Since cryonics is considered a form of interment, whether the person was completely turned into a glass sculpture or straight-frozen like so many people were does not affect the organizations). Doctors may forget rectal plugs or leave patients if funds are unavailable, though.

What do you define as 'very recently'?
