Their rights to an extremely generous and updated tablet based ebook selection.
The ROI on that providing that would be very good for governments, you would assume.
Recidivism down. Libraries could do other things with the book space.
The great thing about prison tablets is that they are cheap and offer a low-cost selection of reading materials, with no incentive to have some scummy third party company in the loop to profit off their monopoly.
The first thing prisoners will do is destroy the tablet. I'm okay with both restricting prisoners' abilities to get direct mail, and I'm okay with allowing subscriptions go directly to the prison library. I am not inclined to want to give prisoners more privileges and I am inclined to remove as many privileges as possible, especially for first time offenders so that they realize that the path they are on is the wrong one.
