So, it doesn't bother you that it is based on an absolute, indisputable, lie?
I'm not totally sure that it is, or ever was a lie. Law enforcement investigating law enforcement doesn't impress me, nor does it represent gospel truth. We were only given one side of the story, the dead man couldn't give his. No one actually saw Mr. Brown reach for the officer's weapon, since that took place inside the patrol car and no one could see what was taking place at the time. The blood could've happened due to Mr. Wilson scratching or injuring Mr. Brown. We have no video evidence, only the word of the cops that did the shooting. Also, many witnesses were dismissed for allegedly lying or misrepresenting the truth. Yet, two construction workers seen on video a second after the shooting, clearly said to the camera that Mr. Brown did indeed have his hands raised at the time of the shooting. Yet, no more was ever heard from those two eye witnesses.
Yes, I still have doubts as to what actually took place the few seconds before the killing of Mr. Brown. His head being down could have been due to severe pain from the first shot, and not due to a "charging stance" as some have claimed. There were witnesses for both sides, but some witnesses were dismissed because they had versions that differed from that of Mr. Wilson, the only person that could say for sure exactly what happened inside the patrol car.
When one branch of law enforcement investigates another branch of law enforcement, yes, there is a question as to the validity of findings. Remember, no independent outside sources were used to examine evidence. The Department of Justice, Missouri state labs and investigators, and local authorities conducted the inquiry. So, considering that scenario, yes, there is doubt as to what actually took place. Also, if anything is based on a lie, as you put it, the "lie" is still disputable as to whether it is a lie or not.
