It does if the cops charge you with Evading Detention or Arrest in a Motor Vehicle, which makes it a felony. This is a legal joke, but I know many ADAs would would try.
Again the use of force or deadly force has to be justified to defend one's self, another, property, or make an arrest or prevent escape. Four justifications. We can eliminate property. As the dude is going away from the shooter or other cop, I see no justification for self or the other officer. So that leaves us with to arrest or prevent escape.
The leading case is Tennessee v. Garner, 471 U.S. 1 (1985)
which is used to claim that the use of deadly force against a fleeing suspect who has committed a felony was necessary to prevent the escape and 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, which is essentially codified in all state penal codes to conform to the minimum standards in Garner to be constitutional.
In Texas, that is Texas Penal Code 9.51.
Below is Arizona's version - 13-410. Justification; use of deadly physical force in law enforcement
C. The use of deadly force by a peace officer against another is justified pursuant to section 13-409 only when the peace officer reasonably believes that it is necessary:
1. To defend himself or a third person from what the peace officer reasonably believes to be the use or imminent use of deadly physical force.
2. To effect an arrest or prevent the escape from custody of a person whom the peace officer reasonably believes:
(a) Has committed, attempted to commit, is committing or is attempting to commit a felony involving the use or a threatened use of a deadly weapon. (here: felony aggravated assault of the employee or cop working security)
(b) Is attempting to escape by use of a deadly weapon.
(c) Through past or present conduct of the person which is known by the peace officer that the person is likely to endanger human life or inflict serious bodily injury to another unless apprehended without delay.
(d) Is necessary to lawfully suppress a riot if the person or another person participating in the riot is armed with a deadly weapon.
D. Notwithstanding any other provisions of this chapter, a peace officer is justified in threatening to use deadly physical force when and to the extent a reasonable officer believes it necessary to protect himself against another's potential use of physical force or deadly physical force.
