I think you on the other hand overestimate how dangerous things can be. You have exposed your set to a biased set of stories with a predetermined ending.
Like consider the following scene. A drunk man. He is lighting the fuses of small explosives and rockets shoot into the air. Then he stumbles into his house and finds his gun. He goes back out laughing and screaming. People look at him scared, what is he gonna do with that gun? He starts firing. Straight into the air. Happy new year!
People do this. They do this and live. Most of the time.
Those falling bullets do kill people though. Rarely is it the one who fired it or anyone nearby but a few people do die every New Year. Far more than can be justified with "It's just a prank, bro."
