And we're still hearing only Lamborn's side of it. I guess that is too fine a point for some to realize. The leaders will neither confirm nor deny this, like you said, the leaders in the Church of Jesus Christ of Latter-Day Saints have an obligation to keep the information about excommunications private. Lamborn must really have been leading people astray, I've never heard of a letter being read in all the wards in a stake. In fact, I've never heard a letter read in Relief Society concerning excommunication.
To do so is to assume certain 'facts' which as NOT on the evidence table.
