How To Tell If A Classmate Is Dangerous

How can I tell if a classmate is dangerous?

There are some signs and symptoms of dangerous people. For example, if someone threatens you and says, "I want to harm you" or " I want to kill you." If they articulate that they want to commit an act of violence towards you. That's one sure way to know if someone is dangerous. If they're talking to you and they say they want to harm someone else, a teacher, or a principal, or another student, that's another way to know that a child is dangerous. If they're engaging in gang behaviour. If they say, "I'm a part of a gang" and they want to commit some type of act of violence, that's a good way to know that you have a dangerous person on your hands.
