It will be up to districts whether they want to allow teachers to be armed. Critics of the bill said it could make classrooms more dangerous to students.
The teacher, a reserve police officer, discharged his firearm during a lesson. Debris fell from the ceiling, and no one was injured. The teacher has been placed on leave.
No students were in the classroom when the teacher fired the weapon, and despite a chaotic lockdown, the only injury was a student who hurt her ankle running away.
