1) It is not reasonable to assume that one person took on six armed people, seasoned hunters by the way, in a straight-up firefight and somehow came out on top. I don't care if he was a "sharpshooter" in the army - mofo never done time overseas as he was just the National Guard...you and I can become the National Guard! It's not the special forces here, people. Even an active infantry unit US Marine could not win a straight-up firefight against six civilian hunters and if you think so, you watch too many movies, play too much Call of Duty, and you're a fukken retard. Therefore, based on reasoning, logic, and the testimonies presented, it is COMMON SENSE to assume that there was in fact, only one gun among the shooting victims.
2) Most of the victims were shot in the back. Not one, not two, but several. Also, if I recall, at least one person was shot while down. Six armed gunmen versus one guy and this one single guy doesn't retreat but in fact, moves in closer, shooting people as they run and finishing them off. You don't shoot someone in the back or when they are down except for one reason - intent to kill. If you still think that he isn't the aggressor, you are so retarded.
3) When Chai Vang finally left the zone, he came across two hunters and claimed he was lost. These two guys gave him a ride out of the area but soon realized that Chai Vang was the suspect in the shooting that day. The first thing a guilty person does is what prosecutors call "distancing themselves from the situation". They want to get out of the scene as soon as possible and as far away as possible in order to avoid being associated with the situation. If six guys were shooting at you and you ran away, running into two other hunters, what would be the first thing you do? "HELP ME!!!!!!!!!!! HELP!!!!!!!! GET ME OUT OF HERE! CALL THE POLICE!!!!!!! THERE'S PEOPLE TRYING TO KILL ME!!!!!!!!!!!" An innocent person has nothing to hide and would tell the truth immediately. When someone lies, they have a motive to lie.
4) Minneapolis police has had numerous calls to Chai Vang's house, most of which involved violence towards his wife. None of the these calls ever amounted to an arrest (I think maybe one did) but it does show that he has the capacity for violence. If he's willing to hurt his own wife, imagine what he could do to strangers in the woods if they simply said some words to piss him off.
Don't be a retard. Be objective and use reasoning, logic, and common sense. This isn't self-defense.
