Sounds like it could be worse to be honest, british prisoners are treated worse than that in some places
My Grandma's Uncle was a prisoner of war and spent up to 6 hours a day for nine days being hung up by his thumbs. At least things don't seem quite as bad now, uncomfortable conditions are better than torturous ones at least. As for some of them being beaten up, I don't think we know why they are prisoners...if someone had murdered someone and was put in a prison in the UK, I expect many would say they deserved to be beaten up
They ought not be beaten up etc, but at the end of the day with being disturbed in their sleep and things, it doesn't sound as bad as I expected the article to be. I can't say much because I don't know why they are prisoners etc, not right to physically hurt them though, as a starting point.
