And if people are going to blame liberals and transgender people for like 1% of school shootings, what laws would have prevented this?
I do not mean that teachers should have guns. I don't think it would be safe for teachers in most situations to carry guns.
What I do mean is that Deans and Principals and the security staff should all have guns. Those guns could be in locked cabinets. You need someone watching the front door of the school who can instantly press an alarm if someone carrying a gun enters the building they sound the alarm. Teachers lock the doors and people on every floor have guns along with monitors so they can see where this person is. Even if you can't put monitors in every room you have one person in a secure room with all the monitors who goes on the radio (all deans carry these radios) letting people know what they see (how many shooters, what they look like, where they are).
