If that's not true, why it is that school shootings are far more common in California than in Texas (California being the state with the highest number of school shootings)? In Texas, teachers are usually armed. In California, teachers are almost never armed.

Know a lot about Texas teachers, do you?

I live in Texas and have for nearly two decades.  While many teachers may own guns, that doesn't mean they are carrying in school.
