I am surprised by this policy. It seems to be very close to crossing the line drawn by Tenn v Garner. The only two department policies I am familiar with in my state reflect the state's law, below.
Georgia's justification for the use of deadly force is very similar to the post that you made. I might also add that the same DA has charged another person with Aggravated Assault, because in her opinion using a Taser is the use of deadly force.
Any use of force policy is going to be formed to conform with Graham vs. Conner and Tenn. Vs. Garner, if they don't that agency is way, way, way off in left field. The aviation analogy that I would use would be a company that said that they allow their pilots to consume alcohol in flight, as long as the consumption would not lead to impairment. Just like no one would have a written policy that said that, no PD would have a use of force policy that was not consistent with the USSC. I will concede that there are surely instances where the written policy and common practice are two different things. Those places deserve all of our scorn.

(b) A person is not justified in using force under the circumstances specified in subsection (a) of this Code section if he:

(2) Is attempting to commit, committing, or fleeing after the commission or attempted commission of a felony; or
(3) Was the aggressor or was engaged in a combat by agreement unless he withdraws from the encounter and effectively communicates to such other person his intent to do so and the other, notwithstanding, continues or threatens to continue the use of unlawful force.
