There’s got to be another answer.

There isn't. Face the hard facts of life. Why would some nut risk pulling his weapon if he knew he was surrounded by people who would shoot him down? The fact that so many would be carrying terrifies these cowards. And these wacko shooters are cowards. Else they would go in police stations instead of schools.

Drop him before he can hurt anyone/ anyone else.
