I was thinking about deep fakes and tech advancements. Yes, that will add doubts etc. but you know what? There always will be ways. If somebody was convicted in 2015 most likely there weren’t any deep fakes.
Let’s look at, let’s say, Apple and its tight control over entire hardware and software iPhone stack. Nothing prevents them to announce that starting from iPhone 19 they cryptographically sign the video to ensure that it’s authentic and, at least, the video and sound are what the camera saw. Pro cameras can do it, for Apple it’s even easier, more or less. I’m sure that even on this site there are experts who can design such system that is as secure as we expect from Apple devices. And that thing will slowly spread due to competitive pressures.

Involuntarily drug testing was one of examples that I gave, and you seem to be against. To some it may be extreme, and I completely understand where you’re coming from. To me… as I said - for some examples from the side the murderers surely lost their human privilege. That comment summarized my feelings after reading the website in much more succinct form: https://news.ycombinator.com/item?id=47302490#47305803
Killing 13 month infant, putting bleach on 20 yo gas station employee and setting her on fire, stranding female who was screaming for help during sa. Mate, if your kidney is compatible with someone who is in need, you made your choice way too long ago to have any right to say anything now. Or if there are other uses that will benefit society and humanity as a whole - they are allowed. You are guilty (without doubt and with clear evidence) and sentenced to death. Now you have same amount of rights as cadaver on the table, but probably more uses while you still breathing.
The problem is that I do understand you! I do feel exactly as you do! My lizard brain would like to do all sorts of horrible retaliations to those people who performed such abhorrent acts. I get it, it's natural.
But I think that society should prevent this kind of basic instinctive response to become the way that we collectively handled those monstrosities, mainly because those punishments will be abused against innocent scapegoats.
