If they want a REAL education, I’m good with that. But, their computers should be programmed with the course material, including all reading assignments and only the research material needed to complete the course. Access to the WWW should not extend beyond that. I suppose monitored emails to family members only could be allowed, as well, though writing a letter instead, wouldn’t hurt them.
They have phones on their units, and in the yard in NY prisons, and they get five free stamps a month (maybe more since I've been retired 15 years), plus can purchase more stamps at the commissary. There's no need for them to be able to email anybody.
