To get back on topic,,,
The Jail that I have been in opened all mail, and kept many articles until i was released.
This is reasonable.
They had a cleaning schedule that was adhered to. Your safety is considered, and your basic health needs are considered.
They offer counseling, education, access to a legal library.
You have 0 privacy in all matters.
You can be restrained at any time they choose with physical force. I'm pretty sure everything I mentioned is legal.
That being said,, the lights are on 24/7, you are in a room with dozens of other men convicted of a-z crimes, it is loud 24/7, you need to be on alert 24/7. you see people get their heads smashed in. This of course is not healthy which is arguably against rights still retained as a prisoner
