If you want to be one, that's a different career path with different qualifications.
That being said, you CAN bring in the school guidance counselors, resource officers, and the like, to discuss this issue with your students if you like. If it's a systemic problem at your campus, this is a MUCH bigger issue than you can solve on your own.
