I didn’t mean solitary confinement. The prisoners can interact with other people during their sentence, just not with others prisoners.

just want to add that you are correct imo. confinement was overall the very worst experience of my 18 years in prison.

I can imagine that is true. I think OP has some rationale, but he/she has done very little second order thinking of the consequences of such isolation. It's very easy to make such harsh armchair statements on the Internet, but I think more reflection is needed.

As I explained above I didn’t mean solitary confinement. I meant simply not mixing with other prisoners. They should be able to see counselors, educators, visitors, etc.
