It’s sad that there has been another body snatching case. Losing a family member is tough enough without having to put up with battles over the corpse. The wishes of the deceased (who nominates a next of kin or executor) should be respected, even if you disagree.
The problem with the Police having failed to take action in the earlier case, despite explicit court orders, is that there is no incentive to obey the law now. Yes it is nice if people obey the law just because it is the law, but for some that is not enough so you need a fear of punishment to act as an incentive.
If people saw some hefty fines, or worse, for people breaking court orders in relation to these matters, then they might not act quite so selfishly.
