I haven't heard this story of the boy getting suspended because he made a gun. Was it a real gun capable of actually harming someone or a toy gun?
And if it's a toy gun, does it look enough like a real gun to cause a panic? And, did he bring it to school? These are all important. Using a real gun at a shooting range: Harmless. Making a fake gun that looks real and bringing it into school = Yelling 'Bomb' on a plane.
