As to the conversation you two are having:
IMO, the eye-witness account that most closely matches with the forensic report is the one from the construction worker:
A construction worker at the nearby apartment complex, who spoke to the St. Louis Post-Dispatch on condition of anonymity, said that he saw Brown running away with Wilson 10 to 15 feet behind. About 90 feet away from the vehicle, Wilson fired a shot at Brown, whose back was turned. Brown stumbled, stopped, put his hands up and said "OK, OK, OK, OK, OK." The worker believed Brown had been wounded. With his hands up, Brown began walking toward the officer, at which point Wilson began firing at Brown and backing away. After the third shot, Brown’s hands started going down, and he moved about 25 feet toward Wilson, who kept backing away and firing. The worker was unable to discern if Brown's movement toward the officer was "a stumble to the ground" or "OK, I'm going to get you, you're already shooting me." The worker disputed the claim that Brown rushed at the officer, "I don't know if he was going after him or if he was falling down to die. It wasn't a bull rush."In a cellphone video obtained by CNN on September 11, which captured the reaction of the construction worker and a colleague, one of them can be heard saying "He had his f**n hands up." The workers said they were approximately 50 feet away from Wilson when he opened fire. Jeffrey Toobin, CNN's legal analyst said that this video could play an important role in the case."
Also, Lestov, I posted in this thread some police protocol. It says to meet lethal force with lethal force, not shoot to wound.
Here is a post I wrote regarding that notion:

You're not correct especially because you referenced CA.The use of a firearm is justified, by most police departments, if an officer determines that the use of lethal force is necessary to prevent serious bodily harm (or death) to him/herself or others. If Wilson was treated for an assault, there is your justification (still waiting on those medical records that show Wilson was beaten...).
If he was beaten by Brown in his car, this is justification enough to use lethal force. Lethal force can be a taser or firearm (tasers are considered the less-lethal options).
Here is some stuff from the Cincinnati PD that I found:
