I have studied...maybe trained for and become informed on are better words... for these types of force incidents.
An officer usually ends up shooting what he is looking at...especially under extreme stress.....we tend to look at people’s hands...A LOT...due to the fact we are always looking at hands for weapons.
I can easily see an officer facing a charging behemoth such as Mike Mike and still focused on his right hand then transitioning to center mass as the threat closes in on him.
This fits with the autopsy results posted in this thread.
The officer attempted to stop the perp with non lethal shots, right hand and arm focus. Didn’t work. Someone keeps charging you go for the kill shot. Brown’s size pretty much guaranteed it would be officer down had he reached Wilson.
