Tyre Nichols death: SCORPION Unit 'permanently deactivated'
The five former officers charged in the incident were in the unit.
Officials in Memphis, Tennessee, released dramatic body camera footage Friday of the fatal confrontation between Tyre Nichols and five police officers.
Nichols can be heard screaming "mom" several times during the gut-wrenching clips, which appear to show officers beating and pepper-spraying him after he ran from a traffic stop arrest.
Nichols died at the age of 29 on Jan. 10, three days after the violent confrontation.
The five Memphis Police Department officers involved in his arrest -- Tadarrius Bean, Demetrius Haley, Emmitt Martin III, Desmond Mills Jr. and Justin Smith -- were fired and then charged with second-degree murder in connection with Nichols' death.

Police departments react to video footage
Some major police departments released statements condemning the actions of the former officers seen in the body camera video of Tyre Nichols' encounter.
The LAPD tweeted a statement from Chief of Police Michel R. Moore, who called the ex-cop's actions "incredibly disturbing, cruel and inhumane."
"The violation of trust tarnishes our bade and has a caustic effect on the public's trust," Moore said in his statement.
Acting New York State Police Superintendent Steven A. Nigrelli also condemned the former officers.
"We are outraged and sickened, and we also understand the frustration being felt by the public," he said in a statement.
EMTs not visible in video until over 22 minutes after beating ends
Among the four videos released by the city, the overhead surveillance wide-angle shot taken from a city surveillance camera offers a bird's-eye view of the beating. The footage is graphic and contains images that are disturbing.
Based on that footage, it appears that roughly 20 minutes lapse between the ending of the beating and the officers' first attempts to render aid to Nichols. EMTs are not visible in the video until more than 22 minutes after the end of the beating.
Additionally, there appears to be several more officers on the scene other than the five who were fired and charged in this case. Shortly after the beating ends, several other officers can be seen in the video. Those officers have not been identified. The local district attorney has said that more charges could be possible in the case.

No body-worn camera video footage lost: City officials
All of the police body-worn camera footage from the fatal traffic stop of Tyre Nichols has been accounted for, the city of Memphis said in a statement on Sunday.
The initial traffic stop of Nichols involved three officers, including one who did not activate his body-worn camera, city officials said. That camera was not turned back on before the officer left the intersection where the traffic stop occurred, officials said.
Video from the body-worn camera of a third officer was preserved and titled "Video 1" in the public release of it on Friday, officials said.
Only two body-worn cameras were activated after police officers chased and caught Nichols, city officials said. A stationary city security camera captured the officers beating Nichols, city officials said. Those videos, described as Videos 3 and 4, were released to the public.
