Something like 80% of crime are down to drug addictions. Send them to enforced rehab with counselling, for at least a year, leave with an implant. That would be money better spent than locking up serial shop lifters, prostitutes etc.
Op I'm so sorry this happened to your family, but I can understand your dh wanting to put it behind him now, maybe you could talk to victim support if you find you can't let it go? Good luck.
