In 1864, Chivington said, "NITS MAKE LICE" in reference to the Indian wars...
That's unfortunate. I wouldn't be proud of it repeating it in either context. I assumed you were referencing this since it was a thread about Mormons.
The Haun's Mill Massacre - Wiki
On October 29, this large vigilante band of some 250 men assembled and illegally entered eastern Caldwell County. Built along Shoal Creek, Haun's Mill was one of the earliest Mormon settlements in Caldwell County and it was a way station on the route from the east to Far West. When the Missourian raiders approached the settlement on the afternoon of October 30, some 30 to 40 Latter-day Saint families were living or encamped there. The mob opened fire in a surprise attack, which sent the Latter-day Saints fleeing in all directions. While Mormon women and children scattered and hid in the surrounding woods and nearby homes, Mormon men and boys rallied to defend the settlement. They moved into a blacksmith shop which they hoped to use as a make-shift defensive fortification. Unfortunately, the shop had large gaps between the logs which the Missourians shot into and, as one Mormon later recalled, it became more "slaughter-house rather than a shelter" (Lee, p. 80). The mob gave no quarter. After most of the defenders in the black smith shop had been killed or mortally wounded, some of the Missourians entered to finish the work. Finding 10-year-old Sardius Smith hiding behind the bellows, William Reynolds of Livingston County shot and killed the boy, saying: "Nits will make lice, and if he had lived he would have become a Mormon" (LeSueur, p. 167).
In all, 18 Latter-day Saints were killed in what came to be called the Haun's Mill Massacre. Most of the remainder made their way as best they could to Far West, where news of the massacre created feelings of grave anxiety.
Wiki actually describes it mildly. His 8 year old brother testified in a court affadavit seeing his brother's brains bllown out all over the wall.
There is a difference between a crossfire and murder.
