From what I read, she was praying for US troops to come home “safely, packed tightly in wooden boxes.”
Also was calling for nazizionist scalps.
Pretty violent rhetoric.
Violent rhetoric, but I don’t see any evidence she committed a crime (unless saying something like we should turn their desert into a glass parking lot is also a crime).
I would expect a higher threshold for FBI involvement. Maybe that threshold was met by details we haven’t seen yet.
