You won't believe this, but my best friend is so into World War II reenactments that he brought a real M1 Garand to our school!
Wow, I can't believe he brought a real gun to school! What happened?
The teachers confiscated it and called the police. They were worried he was going to shoot people.
Your friend shouldn't bring guns to school. People could have been sent into a panic because they were afraid of a mass shooting incident. These careless actions caused everyone a lot of stress.
He wasn't going to shoot anyone, just show it off since we were talking about World War II. Everyone overreacted.
I know it seems like it's not a big deal because you know your friend, but the other people don't know him or what his intentions may have been. I'm sure you can see why because of all the mass shootings at schools over the last few years.
