A 17-year-old from Nebraska and her mother are facing criminal charges including performing an illegal abortion and concealing a dead body after police obtained the pair’s private chat history from Facebook, court documents published by Motherboard show.
There is no such thing as a private chat on a platform you do not own. And even if you DO own the platform it is only as private as the participants decide it to be. Hopefully people start to realize this before complete non-privacy becomes the accepted norm.
Private doesn't means the privacy in this case just a formal formatting. If they were not discussing in a publicly available chat then it is already considered private by the definition but yeah, 99% true.
