Let's start with clear sides at least. >If you touch a child; woodchipper >If you harm a child; woodchipper So that's a good start I suppose, now let's take one step towards the grey area. >If you hire the hitman, woodchipper >If you pay the hitman, woodchipper Doesn't seem too bad yet, but what about father paying ransom? >If you kidnap a child? What about father saving his son from the demented mother? Okay so perhaps it should be limited to sexual activities >Nude photos? Hidden cams? Morally wrong, but what about medical professionals? >Specific licensed professions have highly specific exemptions, with proper data management procedures. >Parents can have nanny cams, with age restrictions As you can see, this quickly becomes a legal mess, and this is the whole purpose of trial by jury, and can easily lead to mob justice as well. An easy answer would be decriminalizing possession and transfer, but you don't want to encourage the behavior either. I'd say woodchipper for those who actively harm, and data centers have zero liability for encrypted data.
