Innocent Fun
My ex-partner’s younger brother brought in a water gun (like those cheap, neon orange dollar store ones) when he was in 4th grade. A 4th grader doesn’t have any malicious intent when it comes to that.
The brother got expelled immediately, and they actually had to move to a different town because there was no school he could transfer to. It seems so extreme to do that to a child when his intent was probably positive.
