We hear about it time and again. Sentences being halved, dangerous criminals allowed out before serving their time in prison, day release, open prisons. A lot of these offenders know exactly what to say to those professionals who make the decision whether to move them to open prisons or release them. Sentences should be served to the very last minute. Time off for good behaviour, my foot. The criminal was found guilty of a crime, that's why he/she is inside, whether they become a paragon of all the virtues during their sentence should not mean they serve less time.
