Any chance of a little perspective here?
The prisoners involved were already in a recovery programme and making the progress we would all want - to get them off drugs. On arrival at prison, the continuation of the programme was denied to them - and that is the abuse of their rights.
On the surface, it's really easy to bang on about 'getting what they deserve / PC gone mad / compensation culture' etc. etc. but if you take an objective civilised look at the situation, it's not quite that simple.
Our laws providde a tarrif of sentences for crimes. They don't include pulling teeth with pliers, electric prods to genitalia, starvation, and so on. Neither do they include inhumane treatment of human beings who are in the process of being weaned off drugs which they have embarked on due to a complex series of life-style situations which those of us who are employed, intelligent, and supported, don;t have to encounter.
It is really easy to take the knee-jerk right-wing view that these people don;t seserve or help and compassion, but in the interests of stopping the vicious circle of drugs / theft / prison / drugs - they actually do.
Human rights are there to support all of us - not just those the self-righteous feel deserve them based on their own lifestyle and code of ethics.
Support and education are the route to curing addictions, not lofty sneering and self-righteous abuse. If we want to be a civilsed society, then understanding this situation, and the people involved.
Be nice!
