Yeah, psychological torture is part and parcel with incarceration, with varying degrees of severity depending on where in the world you are. In Mexico, they aren't legally required to feed inmates.
That is something I wondered about how it would work in SR.
With extraterritoriality many prisons would run their own laws. So its technically possible that you would be imprisoned for something that is technically legal inside the prison under Lonestar law.
Also, LS won't build a prison for every customer. In some regions its entirely possible that a prison receives prisoners from different customers, say the UCAS government in the form of the Seattle mayor, some AA rated corp and a near NAN country.
Imo each contract would include the minimum acceptable treatment of prisoners. So the UCAS contract would specify that prisoners with legal SINs are granted basic human rights, prisoners which come from the NAN contract would have greater religious freedom and LS can't forcibly install cyberware and stuff like that. On the other hand they can legally remove and sell any non-essential ware from prisoners and don't have to return them.
Prisoners from the AA corp on the other hand have no rights at all as the corp will only send people there they have no use for and can be tortured at will if the guard wants to blow off steam.
So prisoners would likely have some implanted chip/AR tag indicating what rights they have among other things.
