I watched the video and read some background, basically my understanding is that the entire series of events went like this, at a high level:

The guy in the hotel room had been showing someone his pellet gun. Someone saw this through the hotel room window, thinking it was a real gun, and called the cops.

The cops arrived, expecting someone armed and dangerous. They seem really amped up on adrenaline.

A woman and the man come out of the hotel room, and the cop with the assault rifle screams at them to get down on the ground. They comply, but seem scared and confused. The cop asks if they are drunk, which they deny. He asks if they'll be able to understand all his commands, and they say yes. He keeps screaming at them and cutting them off when they try to talk.

The woman follows instructions and is successfully cuffed and taken away. The man tries to comply, but is sobbing and appears drunk. The cop gives him some (what seemed to me) not entirely clear instructions, and then tells the man to crawl toward him. After about 5 feet the man seems to lose his balance and try to pull up his pants, at which point the cop repeatly shoots him.

At the end the two cops try to get in to the hotel room, but the key cards they are given don't work. The second cop drops a key card after trying it a handful of times, picks it up, and keeps trying, seemingly extremely agitated. The video then cuts out.

As the suspect was crawling toward the police, he moved his right arm to adjust his pants. Bang, dead. None of this would have happened if the sergeant hadn't given many contradictory instructions to the drunk victim. The team was allegedly afraid of an ambush from the adjacent room, but they throw any caution to the wind straight after that. That video is a masterclass in incompetence. Neither the sergeant nor the shooter received any meaningful punishment.

imagine a man face down on the ground with his hands behind his head and his legs crossed in a narrow hallway. the man is sobbing in terror, and drunk. two cops are pointing assault weapons at the man and screaming at him from 20 feet down the hallway. eventually, they shoot him.
