Man if that could work I'd be so happy. People just say they didn't know better and in the US at least you often need intent, so this would be very difficult to work in current US law. Hopefully it will work better in Wales
The number of people in jail/prison in the US because they didn't’ know better, is staggering. So the standard is already in place. I see no issues with dumping the worst crooks out there, in prison for being ignorant.
