I wonder how many people have been unjustly imprisoned between planted evidence, made up evidence, and illegal parallel construction…
Consider all of that can be used for forced confessions and forced plea bargains also. In those cases, the "evidence" doesn't even need to exist at all, or be on the record in any way.
Sadly, there's more evil and more laziness/incompetence in the world that's being accelerated by AI than there is good.
Over all time? Probably tens of millions.
Here in the US? Probably a large double-digit percentage of cases imo…
