What's a BAR? Obviously you're not talking about a place to drink beer.

True. And I thought assault rifles were banned or fully automatic machine guns that the media seems to talk about endlessly. You can tell when a shooting is done by handgun how quickly it’s out of the news cycle

It's closer to "ice cream sales cause drownings".

A government becoming more totalitarian WILL reduce crime, to a certain breaking point. Part of that totalitarianism could be gun grabbing. As pointed out in a post above, the timeline they quote ALSO had massive draconian (and nowadays labelled "racist") crime reforms that were likely the real primary contributor to the criminality stat: Both "variables" were results from a third related variable.

Much like high temperature causes both more people swimming and thus drowning, as well as ice cream sales, they can be correlated, they ARE correlated, but they're both caused by a third agent. Buying ice cream won't result in someone drowning, and drowning someone won't result in Haagan Dasz's stock price going up. Draconian governments feel no guilt at stopping random people in the street and strip-searching them for drugs or weapons, reducing crimes related to these things. Likewise, draconian governments grab guns.

It's a minor but important distinction from your example, where the variables aren't actually really correlated at all.

Exactly.

Muh fucking peaceful Pocahontas people.

hahaha, i was making a point from his ignorant perspective. Pointing out the irony in his behavior, like would he be saying that about his tribe in taking away their weapons.

And here's the official Army account (Atlas of the Sioux Wars):

Big Foot eluded the cavalry patrols trying to prevent his movement to Pine Ridge by traveling through the Badlands. Therefore, Miles ordered the 7th Cavalry, commanded at the time by Colonel James Forsyth, to intercept Big Foot’s band, disarm them, and march them to a railhead for movement to Omaha. On 28 December 1890, advanced elements of the 7th Cavalry located the elusive Sioux and escorted them to a campsite along Wounded Knee Creek. The remainder of the regiment arrived at the campsite that night. The Sioux awoke the next morning to find themselves surrounded by 500 soldiers and 4 field pieces. Big Foot’s Sioux, with perhaps 120 men and about 200 women and children, recognized the hopelessness of their situation and agreed to be escorted to the railhead for transportation back to the reservation. The old chief was stricken with pneumonia, so the Army provided a heated tent for his care. Forsyth did not expect resistance when he deployed his units to disarm the Indians. However, the Indians grew increasingly upset as the soldiers searched the lodges and clothing of both men and women. The situation suddenly grew more volatile when a medicine man named Yellow Bird called for the warriors to resist. During one search, a soldier and an Indian scuffled for a rifle and the weapon accidentally discharged. Both sides opened fire at brutally close range as the women and children scattered in panic. The artillerymen on the hilltop added to the mayhem when they opened fire on the fleeing Indians. The fighting ended when the Indians fled the battlefield. On the field lay 150 dead Sioux, including Big Foot. The immensity of the tragedy was magnified in that at least 62 of the dead were women and children. The Army suffered 25 officers and soldiers killed and another 39 wounded. Miles was furious over the whole mismanaged affair. He relieved Forsyth of command (the decision was later overturned) and skillfully avoided further violence with the bands associated with the Ghost Dance.

You forget the part where they were starving, and this is not what happened at all (there was no attempt to arrest anyone in particular but just a scuffle over one rifle with a deaf guy leading to a discharge, after most rifles have been handed over, there was no "lengthy speech" only one guy dancing around and shouting in a trance, and "robbing soldiers" was capturing weapons to shoot back, at first using knives in the melee in the gunsmoke because again they have been disarmed before they were fired upon and actually the soldiers also likely hit each other).

The guy made up his story, pulled it from his ass.

Here's one actual account (Encyclopedia Britannica):

On December 28, 1890, the 7th Cavalry, commanded by Col. James W. Forsyth, reached the Miniconjou camp near Wounded Knee Creek, located roughly 20 miles northeast of the Pine Ridge Agency. The late Gen. George Armstrong Custer had led the 7th Cavalry to its demise at the Little Bighorn less than 15 years earlier. Big Foot saw Forsyth’s scouts and informed them that he would surrender without resistance. On December 29 Forsyth convened with the Miniconjou to begin the process of weapons confiscation. He herded them into a nearby clearing, had their men form a council circle, and surrounded the circle with his cavalry. He also positioned four Hotchkiss guns on a hilltop bordering the clearing.

Forsyth was clear in his terms: the Miniconjou must surrender all their weapons. Big Foot was hesitant, but he surrendered a few guns as a token of peace. Forsyth was not satisfied and ordered a complete search of the people and their camp, where his men discovered a host of hidden weapons. The increasingly intrusive search angered some of the Miniconjou. A man named Sits Straight began to dance the Ghost Dance and attempted to rouse the other members of the band, claiming that bullets would not touch them if they donned their sacred ghost shirts. The soldiers grew tense as Sits Straight’s dance reached a frenzy. When a deaf Miniconjou named Black Coyote refused to give up his gun, the weapon accidentally went off, and the fraught situation turned violent as the 7th Cavalry opened fire. Because many of the Miniconjou had already given up their weapons, they were left defenseless. Scores of Miniconjou were shot and killed in the first few moments, among them Big Foot. Some women and children attempted to flee the scene and sought protection in a nearby ravine, but the Hotchkiss guns fired on their position at a rate of 50 2-pound (0.9-kg) shells per minute. The Miniconjou who were able to make it a little farther were cut down by the mounted soldiers. The 7th Cavalry did not discriminate.

Immediately following the massacre, Forsyth ordered the transportation of 51 wounded Miniconjou to the Pine Ridge Agency. Hundreds of Lakota who lived there fled the area in horror; some even ambushed the 7th Cavalry in retaliation, prompting Miles to dispatch more troops to the area to quell further resistance. On January 2, 1891, a band of Lakota went to the site of the massacre and rescued a few survivors from the snow. The following day the U.S. Army unceremoniously buried 146 Miniconjou in a mass grave where the Hotchkiss guns had been placed, a location today known as Cemetery Hill. Many of the corpses were naked. Modern scholars estimate that between 250 and 300 Miniconjou were killed in total, almost half of whom were women and children. At least 25 U.S. soldiers also died, many likely fallen to friendly fire.

In the mentioned aftermath ambush, they were trapped in a narrow canyon and would have been massacred in turn if the (other) cavalry didn't come to rescue. This was less then 24 hours later. They were some really poor soldiers under really bad command.
