Fewer than 80 people in 5 years. Non payment of council tax is not the problem for the prison system.
The problem is similar to hospitals and bed blocking. Many prisoners have to demonstrate their rehabilitation for parole boards - sex offenders have to partake in certain courses for example, there are thinking skills courses, alcohol or drugs rehabilitation work, domestic abuse insight type courses.... But these are not available in every prison and so we shuffle these men (mostly men because women's prisons have totally different problems to men's) around the country to try to get them into a training course but it's not always possible.
We have drug dealers and organised crime groups managing drugs rings from their cells, staff corruption up the ying yang, drugs overdoses on a daily basis, prisoners needing shipping out because of debts and a price on their heads....
There needs to be huge investment in the prison buildings which are falling down around the ears of staff and prisoners alike.
There needs to be massive changes made to educational programmes and availability provided in far more prisons for the specialist courses for rehabilitation. And more incentive for basic maths and English to be completed by illiterate prisoners. We need educational support for dyslexia and so on.
Daily earnings in workshops needs to be reviewed to reduce debts and all the violence that brings. There needs to be more variation in workshop types to expand skillsets and improve the chances of working on release
We need huge investment in dealing with prisoners with autism and other ND issues. Especially where that translates into very violent outbursts.
We need "safety" and "disposal" razors banned from the whole estate and a shift to electric razors to prevent more injuries.
Truly, this is not bleeding heart liberal stuff.
This is a gruesome example of the consequences of the current problems - https://www.poauk.org.uk/news-events/news-room/posts/2021/july/following-horrific-attack-on-an-hmp-swansea-officer-the-poa-urge-hmpps-to-remove-razors-from-prisons/
