Utah law dictates that concealed weapons are allowed in a church, unless the church has posted a written ban at the entrance, or has registered with the State as a "restricted zone."
US Constitutional issues obviously come into play here, and even opinions about self-defense in unknown situations. One person said: "What better invitation to a terrorist to attack a church than to let it be known far-and-wide that there are no weapons for self-defense in that church?"
Not an easy dilemna.
