You had to do that didn't you? You had to make me bring this up (sigh). Maybe you should watch the movie I believe titled "September Dawn".
"A California-bound wagon train of about 140 Arkansas emigrants led by John Baker and Alexander Fancher camped near the present-day southwestern Utah town of Enterprise in September 1857. Fears that the U.S. Army was preparing to forcefully remove Brigham Young as Utah territorial governor and impose martial law were at their height. Spurred by inflammatory sermons of LDS leaders, a siege mentality focused Mormon resentment on the 'gentile' wagon train.
Early on Sept. 7, a group of American Indians and local Mormon 'Indian missionaries' attacked the encircled wagon train without warning. ... With their ammunition, food and water almost gone, the emigrants were persuaded by Mormon officials on the afternoon of Sept. 11 to surrender their arms in exchange for a safe escort past the Indians to Cedar City. ... On a pre-arranged command, the rescuers turned upon the emigrants, joined by Indians who had been lying in wait. Estimates of the death toll include 14 Arkansas men shot in the head, 12 women and 35 youngsters clubbed or knifed to death, with 17 children younger than age 8 surviving the double-cross.
Nine cowhands hired to drive cattle also were murdered, along with at least 35 other unknown victims. In all, 120 people, mostly women and children, were slain." (Salt Lake Tribune, March 14, 2000, p. A-4)
I am forced to conclude that you are woefully ignorant of many cover-ups of the Mormon Church. Here's a book suggestion (absolutely replete with documentation that you need) that will help you out on this subject:
Blood of the Prophets: Brigham Young and the Massacre at Mountain Meadows (Paperback) by historian Will Bagley available at Amazon.com - http://www.amazon.com/Blood-Prophets-Brigham-Massacre-Mountain/dp/0806136391/ref=pd_bbs_sr_1? ie=UTF8&s=books&qid=1197516542&sr=8-1.
Another one entitled The Mountain Meadows Massacre by Juanita Brooks is also available - you can get the complete set! On the other hand if you are too brainwashed to pay money in the interest of truth there is always this website which discusses it absolutely free: http://www.utlm.org/onlineresources/mmm_familysecrets.htm
That’s nice. I said evidence, not opinion.
