Don't entirely disagree, but you could say the same for all murderers who get 'life' sentences. The average murderer spends just 16 and a half years inside.
How fair is that?
Seems a complete fruit cake (with extra nuts) but maybe should be given a chance in an open prison and if he breaks any conditions there, then back he goes to full prison. As said he is 70, so less likely to do so much damage these days.
Considering the average time spent in jail for a murderer...
