Answer: true
Explanation:
Okay let us go through the question again. The student in question Isaac is a disabled person. He had argument with a fellow student and he(Isaac) decided to bring a gun to threaten the student that he(Isaac) was going to shoot the student he argued with. First thing comes first, Isaac has no right whatsoever to bring a dangerous instrument like that to school, a Gun for that matter not to talk of threatening to kill. This is totally wrong of him, but what can we say, he belongs to a neighborhood gang.
So, it is the right and the proper thing to do, that is removing him from that school. And to the answerer, YES,it is TRUE,you are right.
