Sacred dances like this one are not being held anymore because so many of the people are drinking and misbehaving and in truth act like they are out of their minds. People simply do not realize how far the Indians have fallen because of liquor, most only see the surface damage.
Fools Crow Lakota
Here is the fellow who has been puzzling you, especially in his lack of control. He does absurd, incredible, tragic things while drinking. He is a real Dr. Jekyll and Mr. Hyde. He is seldom mildly intoxicated. He is always more or less insanely drunk. His disposition while drinking resembles his normal nature but little. He may be one of the finest fellows in the world. Yet let him drink for a day, and he frequently becomes disgustingly, and even dangerously anti-social. He has a positive genius for getting tight at exactly the wrong moment, particularly when some important decision must be made or engagement kept. He is often perfectly sensible and well balanced concerning everything except liquor.
