Well I think you'd be suspended until it's proven that it was an accidental and that you had no intention of posing like a nazi, something like that probably. But yes, it's kind of getting out of hand, school has to be a safe space for children, to grow up in belief that the world is like school so when they go out in the real world hey get triggered, upset and stuff like that. Modern society.
Probably the worst overreaction.
Well I understand it, they're "not a good example" for the other kids and you know that US deals with quite a few school shooting from time to time so it's kind of understandable but still stupid... I'd understand if it was a teacher doing some stupid stuff and get suspended, but these are kids... :/
