I wasn't actually defending Vang, just applying so many things we talk about here.
People generally say things like "He fires a shot at me, I'm definitely shooting him down."
Since none of us were there ... suppose these guys were swearing at him and threatening the asian guy who dared violate their area. Maybe one did fire the first shot over his head (he says they fired first, the other "victims" say he fired first ... all the jury can do is listen to testimony since the bullets weren't time stamped) in that case most would say, "Oh yeah -- he's using lethal force. Shoot him down."
But if this was what happened, and Vang stopped shooting after taking down the guy with the gun, it's quite possible the results would be the SAME. Still going to prison for life, because the other's worked on their story and made sure they testified correctly as to who fired first.
So to me the point is ... always use your head as your primary weapon before you use anything else. Even if you're in the right (don't know if he was or not) you'd damned well better hesitate before returning fire on a group that large. Chances are you're right -- if the rifle shooter amongst the victims did fire first and WANTED to kill him it would have happened.
How much better everyone's life would have been if Vang and the other's BOTH would have swalled their pride and deescalated this situation.
I do believe that Vang snapped and got the sentence he deserved (since lethal injection isn't an option).
But ... it's also within the range of possibility that this is a man who chose to defend his own life with a firearm against lethal force being presented against him, and as a result is about to face life without parole in prison. No one here can disprove that, and only the people there that day actually know for sure.
Sure ... it's better to be tried by 6 than carried by 4 (is that right?) but if those six send you up the river for life without parole ... you might not have made the right choice.
We all have to choose when to shoot/when not to shoot. Sometimes you have to face the danger and err on the side of not shooting.
