But it is not fantasy. It has happened in the past, and it could happen in the future. How many times have teachers or students, legally armed, intervened in school shootings with beneficial effects? At least four times in the 20th century:
- University of Texas, 1966, armed students and faculty.
- Appalachian School of Law, 2002, armed students.
- Pearl, MI, 1997, armed faculty.
- Parker Middle School, 1997, armed citizen.
