I'd like to be part of an effort to make my voice heard by the church, too, but quite frankly I have dim hopes of how any such effort would be received. Once the First Presidency (or any significant authority) officially signs off on something, it's very hard to oppose them without being treated like an apostate. And the higher church leadership isn't big on taking orders from the little people (which in many cases would certainly be a bad idea). The LDS church is, for better or for worse, very much a top-down authoritarian organization that claims near-infallibility for its leaders (particularly the first presidency). In some cases this is a good thing because it makes it difficult for false doctrines to creep in at the local level and keeps the church reassuringly uniform throughout the world. Unfortunately it also gives misguided leaders a cultural inertia that is very difficult to reverse. Case in point, while in Texas I was in a stake where the stake president decided that the stake would enthusiastically (and without qualification) encourage ALL El Paso members to attend the newly constructed temple across the border in Ciudad Juarez, despite the dangers associated with that city. When a friend of mine, also a member, told the stake president that Juarez was becoming increasingly dangerous for Americans and that the drug cartels had actually put a bounty on the heads of any US federal agents caught in Juarez, he was, in essence, told to shut up and not worry about it. The bounty was of particular importance because my stake had several members who were in fact federal agents, including my friend. (Incidentally, it was about this time that my friend got his first CCP and talked me into doing the same.) In the end, after being brow-beaten and ostricized by those who should have been his friends in Christ, my friend pushed the issue, and the stake president responded by giving a talk at church wherein he promised that "God would protect anyone who went to the Juarez temple." During my stake's first outing to the Juarez temple two cars were stolen, one was vandalized, and a month later one couple narrowly escaped the city with their lives after being threatened by thugs at gunpoint. My friend finally succeeded in persuading some of the people in our stake to go with him to the Albuquerque temple instead. The stake president, with the full support of the stake high council, and in spite of the violence that the members were facing, continued to encourage ALL members to attend the Juarez temple AND continued to try to dissuade my friend from "misleading the Saints" by going to the Albuquerque temple. I guess the stake president wasn't one of the ones whose car was stolen. Or perhaps his idealism blinded him to the venal nature of the real world outside of his perfect little bubble. In any case, the point is that the church expects its members to bow their heads and humbly submit to any and all authority, so good luck trying to change anything with grassroots activism. Please note that I'm not saying that all Mormons are authoritarian tyrants and lackeys. I know quite a few Mormons who are thoughtful, freedom-loving patriots, as I strive to be. I'm just saying that there is a culture of "don't think, just do what you're told" within much of the church.
Sorry to go off topic, but I just wanted to point out some of the difficulties that are likely to be faced by anyone trying to use down-up pressure on the church to restore a wise gun policy. And again, I hope I haven't offended the sensibilities of any Mormons who feel that their church leaders can do no wrong.
By the way, I like the chain of command analogy. I also feel that my God-given duty is at odds with this church policy. While I do understand that if I get caught with a gun at church this will put the Bishop in a moral quandry, I feel that not protecting my family (and fellow ward members, for that matter) is an even bigger moral issue.
And like everyone else here, I am neither confessing to or explicitly encouraging anyone to break the law. Inform yourself, think about it, and then make your own personal decision.
