It was just something my wife asked me and I didn't know the answer, ie
if you freeze adult mature beans before they dry do you still have to
boil them? I think we will boil them any way to be on the safe side!

Yes, definitely. The toxin is produced as they mature, and is not
plausibly destroyed by freezing, but you only have to keep them at
boiling point for 5 minutes or so, which you will be doing anyway.
The most toxic are red kidney beans, and they have harmed some people
who put them in slow cookers on low without boiling them first. The
US FDA is over the top, as usual, but it would be good advice in
places like Boulder.
