Surely if you commit a crime and are put behind bars, you should expect to lose all civil liberties
So if you drive above the speed limit you will accept that you will be imprisoned and lose ALL civil liberties - including right to life, freedom from torture, freedom from slavery and forced labour, freedom of conscience, freedom of religion, the right to due process, and to a trial. Those are your civil liberties.
It seems that you believe that the routine torture of prisioners for minor crimes is perfectly reasonable as you think they no longer have any rights or civil liberties.
Clearly some civil liberties are lost by prisoners who have committed serious offences (freedom of movement primarily), but that does not necessarily mean they should lose the right to vote or wear matching socks.
Roz's ideas for classes on governance makes sense, but I don't see why prisioners need to learn this any more than the 30% of the population who don't vote or those who think that voting for the winner of Strictly Big Brother is more important than for their MP.
