Lost Chicken, I spent many years as a volunteer Prison Visitor, and have visited in eight British prisons, including some high-security ones (called 'A' Category) Most of 'my' prisoners had mental health and drug-addiction issues, and had suffered abuse as youngsters. I felt sincerely sorry for their sufferings, and many had been homeless too.
It's true that most folk in 'society' would like them swept out of sight (a bit like Hitler with his concentration camp ideas)
Compassion is one of the most blessed and treasured emotions to have.
I'm an old lady now, so can't do much to help, except to donate to the relevant charities.
