You have ignored the "fact" that witnesses have reported that Brown was not fleeing when shot, but was instead facing the officer with his hands up. This is why the protesters have been shouting "Hands up, don't shoot". This suggests, strongly, that it was not necessary or time-critical to shoot Brown. Especially "more than two" times (quote from County Police chief).
Also, regarding the "facts" of the case: Ferguson Police Chief's Story on Michael Brown Keeps Evolvoing at http://www.thewire.com/national/2014...-brown/376130/ (I have no idea what The Wire is as a news source, but the article headline caught my eye. This story has changed way too many times for my liking.)
