Brigham Young convinced a LOT of MORMONs that the folks in Missouri were out to EXTERMINATE them all; and managed to put enough fear into a bunch of them that they walked all the way to Utah pulling a handcart.
Too bad the Living Prophet did NOT foresee how many of the faithful would DIE on these treks!
Oh; the ones left behind; how did THEY escape being killed?
GOD only knows, but they received all the property that was left behind by the others: homes, goods, the Inspired Version; etc...
