Justice???re child killer?

So Austen Hughes was released early(?) 16 years after serving his sentence for child killing and there is uproar and outrage. Well we chose the justice sysyem and we implemented it and I believe the mother was also in this horror killing SO LET HIM GO BACK INTO SOCIETY OK??WORSE people walk the streets and havent been charged at all// He has done his allotted time so shut up and leave him be,OF COURSE I DO NOT LIKE HIM but atrocities are committed DAILY nowadays..and a LOT walk free...
