Back to the treadmill?

A 'phone in every jail cell - what do you think?  Very much depends on what you see jail as for, I guess,  There are those who think that imprisonment should be a punishment - it should be an unpleasant experience designed to constantly remind you what a naughty person you are, or at least, have been.  Then there are those who see imprisonment as simply a way of separating those with anti-social tendencies from the rest of us - in which case there is no reason why, as far as possible,  they should be denied the normalities of life - like access to a 'phone.
