I think it's a reasonable point to make. Writing things down is a part of "thought" for many, including those who keep diaries/journals. If you write in a private journal you do so with the expectation that is not shared, and that wouldn't seem to break this law (with my naive reading).

> “written and shared” is illegal all over

I think it’s valid to ask if tapping something into Claude is legitimately sharing a threat.

I don’t think it is. I also think the sheriff could have found more-substantial evidence if she was actually planning domestic terrorism.

That said, if the shooting happened and we were looking at this from before? It’s a tough balance without an easy answer.
