Why should teacher have guns in school? (explain in at least 4 sentences)

If teachers are allowed to have a carry on (gun), it would allow them to protect against a shooter or intruder on the campus they work on. With proper training and discipline they could use their carry on or gun to protect not only their selves but other students. teachers would no longer be defenseless in case of an active shooter situation. The downside is that some teachers may use it to threaten students, but that is why with proper discipline and training teachers could save lives just with a gun on their side.

Teachers should have a gun(s) in school. It could be kept in a box with the teacher only being allowed the key. They would need to go through background checks and training before being allowed a gun. If there were a school shooter, they could protect themselves and their students. It's also good for other school emergencies that require immediate protection.
