TIH: Massacre at Wounded Knee: Disarming the Lakota: 1890

According to Wikipedia,The incident started when troops" went into the camp to disarm the Lakota"  More specifically:

"At daybreak on December 29, 1890, Col. Forsyth ordered the surrender of weapons and the immediate removal and transportation of the Indians from the "zone of military operations" to awaiting trains. "A search of the camp confiscated 38 rifles and more rifles were taken as the soldiers searched the Indians. None of the old men were found to be armed. "On the morning of December 29, the troops went into the camp to disarm the Lakota. One version of events claims that during the process of disarming the Lakota, a deaf tribesman named Black Coyote was reluctant to give up his rifle, claiming he had paid a lot for it.^[6] A scuffle over Black Coyote's rifle escalated and a shot was fired which resulted in the 7th Cavalry's opening fire indiscriminately from all sides, killing men, women, and children, as well as some of their own fellow soldiers. Those few Lakota warriors who still had weapons began shooting back at the attacking soldiers, who quickly suppressed the Lakota fire. The surviving Lakota fled, but U.S. cavalrymen pursued and killed many who were unarmed."

Later, "Former Pine Ridge Indian agent Valentine T. McGillycuddy was asked his opinion of the 'hostilities' surrounding the Ghost Dance movement by General Leonard W. Colby commander of the Nebraska National Guard (portion of letter dated Jan. 15, 1891):^[14]
"As for the "Ghost Dance" too much attention has been paid to it. It was only the symptom or surface indication of a deep rooted, long existing difficulty; as well treat the eruption of small pox as the disease and ignore the constitutional disease."
"As regards disarming the Sioux, however desirable it may appear, I consider it neither advisable, nor practicable. I fear it will result as the theoretical enforcement of prohibition in Kansas, Iowa and Dakota; you will succeed in disarming and keeping disarmed the friendly Indians because you can, and you will not succeed with the mob element because you cannot."

Setting aside the massarcre, is there some insight to be gained regarding today's obsessive gun controllers and gun control efforts aimed at law-abiding citizens?  What's your take?
