@Kimon:
Guns do not function like their video game counter parts, everyone has a certain level of pain tolerance. As long as your body is producing adrenaline and various chemicals, you might not even feel the pain of getting hit while your body is in fight or flight mode.
Now I have heard several versions of the story.
First version:
Brown and friend were off making noise and doing nothing. Officer shows up after noticing Brown fit the description of a store robber, officer then kicks brown's ass. Brown is on the ground in pain and begging and screaming. Officer executes him.
Thoughts: If that is true, why does he have wounds in his hand, arm, corner of his torso, etc when the officer could have shot brown in the head a few times.
Second Version.
Store robbed, brown was out walking around, brown fit the description, officer came by in his SUV, brown grabs the officer through the window of his suv, brown reaches for his gun to defend himself. Brown was six times hit in the places as marked in the autopsy picture.
Thoughts: Possible. People claim he was gentle giant, but his face book says otherwise. Maybe brown made a mistake when chose to grab the officer, maybe the officer said something to provoke him. I don't know which side the officer had this taser on or if he had a taser at all(they aren't standard issue in all departments, some require that you pay out of your own pocket for one). It sounds like the officer made a split second decision while being thrashed around. Maybe brown wished to continue to fighting as the officer brought out his pistol, maybe the officer called brown over and pointed a gun a brown which caused him to react by trying to get the officer to lower his gun.
Third Version: Same the first. Officer gets out to confront brown. At some point brown charges the officer and the officers decides to shoot him which could better explain as that up and down bullet grouping.
Thoughts: Plausible. Did Brown charge out the game? maybe. Could the officer provoke brown into a fight? maybe.
My thoughts on all three. Rashomon effect.
