Prison should be a punishment and not a break from day-to-day life.
To save public money, prisoners should have no access to mains powered devices such as televisions, radios or access to the Internet (if they currently can). Radios should only be permitted if they are battery power but preferably solar-powered (if they are in a cell this won't work) so only wind-up powered radios should be permitted. Prisoners should not have access to mobile phones and to ensure that they can not use smuggled in phones, mobile phone detector need to installed if possibleor 2 years added to their prison sentence if found. Prisoners should not have the right to vote.
