I don’t know. James Upham is credited with inventing the Bellamy salute and may have been inspired by the Roman Empire, or more likely by contemporary portrayals of it. Anyway, by 1930, nobody was heiling Caesar that way, but the salute was in use by American schoolchildren. On that basis, I stand by the claim that the Nazis stole it, directly or indirectly, from either the US, the Roman Empire, or Mussolini’s Italy. It’s a kind of cultural appropriation I find more palatable when done by people who don’t then proceed to violently annex most of Europe.
Local news is reporting the shooter and one victim are dead. The other victim was grazed in the arm and is in stable condition.
