This is a civil case, but as far as I am aware still good law by SCOTUS.
Tennessee v. Garner, 471 U.S. 1 (1985), is a civil case in which the Supreme Court of the United States held that, under the Fourth Amendment, when a law enforcement officer is pursuing a fleeing suspect, the officer may not use deadly force to prevent escape unless "the officer has probable cause to believe that the suspect poses a significant threat of death or serious physical injury to the officer or others." It was found that use of deadly force to prevent escape is an unreasonable seizure under the Fourth Amendment, in the absence of probable cause that the fleeing suspect posed a physical danger.
"Probable Cause":
Passed out in drive-thru behind wheel
Violent Offender on Probation
Intoxicated
Not in a vehicle registered to him
Attacked two officers
Took one of their weapons
Ran from them
Turned and shot one with a deadly weapon
The officer had PC that he could/would harm another person if he escaped.
BTW: Fox had a video of the DA stating that a Tazer is a "deadly weapon" just a couple of weeks ago.
If you want to know where this country is headed with this "politically/culturally" OVERCORRECTION in face of the Black Lives Matter hysteria .... just look at the Atlanta DA ...
I once had the head of a local NAACP chapter in a small White-dominated town tell me that "we" know a lynching when we see one."
Well .... me too! And these Atlanta cops are getting lynched by a MOB and the DA is leading the pack to divert attention away from his own criminal charges and to win an election. It's too bad the DA has IMMUNITY.
Waco ... there is more than one video.
