I agree with most of your comments. I am not convinced that solitary causes mental problems though. Give them a 5” television screen that provides FoxNews, and a radio that pipes in a news channel, and they’ll be okay. Give them access to a lending library on wheels. If they can’t busy themselves, too bad. Avoid prison in the first place.
Give them non responsive access to Free Republic meaning they can only read and scroll but no ability to post.
Then you would really see the ACLU types ranting.
: )
Easier said than done now that the US government has beocme a law-sink where bureaucracies can imprison people.
