I may be wrong too because my adult kids were mever in jail. But I tend to like them to face their consequences without softening it. I dont feel they learn if we make it easier.
This is your sons second rodeo in prison. Not a good track record. He can go to general population like most inmates, work, go to school, work on his addiction and progress. Or he can stay locked up 23 hours and, with your gift, watch TV all day. I would send him non fiction books about AA and Addiction for his birthday. Maybe some true books about adult addicts who turned their lives around. Maybe even religious material. I would rather he read constructively,if he insists on protective custody, rather than watching reality shows and sitcoms. Do you really think he will watch CNN all day? If he likes the news, get him a newspaper subscription. A TV? No way. I feel strongly about it.
If it were mine Id want him where he can get help rather than locked up for 23 hours where he can hide his entire sentence and not grow. How will that help him for when he gets out? You csnt fprcr him to change wherr he is, but you dont have tp reward hom for wasting all the perks that prison offers. He neefs AA, a job, school...not Beverly Hillbilly reruns.
I vote no on the TV. It could harm him. He would do best in my opinion with exposure to healing and how to get over his addiction. You dont want him to do this another round.
