LDS Church-owned Brigham Young University in 1986 adopted a written policy prohibiting employees, students and visitors from carrying weapons on campus.

The policy has been revised several times — but the firearm ban remains intact.

"BYU prohibits the possession (on or near the university campus, including residence halls) or use of firearms, which includes any device which can expel a projectile, and/or other dangerous weapons, including knives, explosives, or other items which, in their intended use, are capable of inflicting serious injury," according to the University Electronic Handbook.

"Because these items pose a clear risk to the persons and property on the BYU campus, violation of this policy may result in suspension from the university; prosecution under appropriate city, state, or federal laws; and/or a $300 fine. A student residing in an on-campus residence area who wishes to bring a hunting or target weapon with him/her to school should check it in with the management of the area immediately upon arriving at school and may check it out just prior to its use. At no time shall a weapon or firearm be in a residence hall."

Exceptions to the rule: Campus police, students who have completed request form to store weapons at a BYU storage facility, ROTC units and the BYUSA shooting club.
