It may seem otherwise, considering the way Old Glory is used as a barometer for any sort of local tragedy, but there are actually Federal guidelines for this sort of thing. The governor of a state may, in fact, order American flags to fly at half-staff, but only under very specific circumstances. And the death of a religious leader -- I feel the need to re-emphasize this, even in Utah: a RELIGIOUS leader -- does not qualify.
Title 4 of the U.S. code spells it all out, and section 7m authorizes a governor to make such an order "upon the death of a present or former official of the government of the state, or the death of a member of the Armed Forces from that state who dies while serving on active duty" (hat tip to USAHistory.org). The head of the LDS Church may be a de facto political figure in Utah, but we can all mourn without bringing the flag into it. (Scott Renshaw)
