I'd say it depends on the age of the kid and if he is the violent type. Also if him parents know that he has the gun. At the worst he should be প্রদত্ত a talk and be suspended. Unless he is older and knows better.
It is a serious matter,whether the gun is loaded অথবা not.A gun is still a gun,and should not be something a kid brings to school to প্রদর্শনী his friends.I don't think the cops should be called,but he should receive detention অথবা something,and his parents should be informed of the matter.But,it's also kind of the parents fault for having a gun where the kid could get it. There have been kids that have brought বন্দুক to school,and those বন্দুক were loaded(and I'm not just talking about teens.I am talking about elementary school kids),Guns are not toys!!!!!!!!!!!!
Absolutely NO way should he be bringing that gun. A gun is still a gun. Whether it's the gun অথবা the person behind the gun causing the issue who's says I can trust the person? For all I know he could have ammo in his locker. And it's still a weapon loaded অথবা not, hit somebody on the side of the head with that thing and they'll go down. And is their really a reason to প্রদর্শনী his friends? A school being at unease isn't worth it IMO. A school would be risking so much for such a little reason. If the guy is 9 অথবা 99, no one can be to safe. I say definitely call the cops just to make sure the kid is emotionally stable, and I'd be curious where the kid got the gun, that's the real question. And then just let the kid off with a warning, making sure he NEVER brings it again.
