If he did that, and he tried to break into Dunn's car, I would feel that Dunn was justified. But I would still think that Dunn should have acted differently (just like I feel that Jordan Davis should have acted differently - but at least his actions didn't cause a death). Some people see this kind of situation as an opportunity to exercise their right to use deadly force, but I but I don't see deadly force as necessary to end this conflict so I don't think it should have been used.
I suppose there may be some people out there who have a gun and are just itching for an excuse to blow someone away. In fact, I know there are because there have been some stories in the news which really, really gave that impression about the shooter. Off hand I recall one where a guy sort of sadistically killed two teens (a male and female) who'd broken into his house, and the other story that comes to mind was that old guy Spooner who shot a 13 year old black kid he suspected of stealing one of his guns, when the kid posed no immediate threat.
EDIT: Oh and that movie theater texter shooter guy is a great example too. That was absurd.
Whether Dunn falls into this category, I cannot say. I certainly don't get that vibe from him in his police interviews. That's not conclusive, of course.
One thing that seems undeniable at this point is that if Davis had kept his mouth shut, and not insisted that Tevin Thompson turn the music back up, and had not screamed "fuck that n----r! turn that shit back up!" - he would be alive today. The question is, did he just give Dunn a flimsy excuse to do what he was itching to do? Or did he legitimately put Dunn in fear for his life?
No amount of backtalk, cursing, disrespect, etc can justify whipping out a gun and filling a truck full of kids with bullets.
But if Davis really did say what Dunn claims:
"I'm gonna kill you bitch, this is going down right now." and started to open the door of the car as he said it, then although it would remain a very unfortunate shooting, I don't think he should go to jail for it.
Based on the first two days of testimony, there is stuff which makes me think Dunn's story may be true. Davis' best friend admitting Davis started to open the door at one point, hesitating a lot longer when he was asked if Davis threatened Dunn as compared to his immediate and confident answers about whether he and the other two did... and the three of them admitting that Jordan, and Jordan alone, got extremely agitated about the request, a request which the others admit was made politely. They also seem to admit that they really didn't hear Dunn curse or act aggressively. All I've seen was one of them say that Dunn had said
"are you talking to me?" and that he seemed upset when he asked it. Most of them also admit that the music was so loud they could not hear everything Davis said to Dunn.
Because of all this, I'm not sure how we can be confident enough that Davis didn't threaten Dunn's life, to feel particularly good about him going to prison for decades. If other people are tapping into some source of certainty that isn't available to me about whether that happened or not, maybe they can direct me to it. Because as it stands, I honestly have no idea if Davis threatened Dunn. It does seem consistent with Davis absolutely flipping out though. Flipping out which is acknowledged by the other occupants, and consistent with "fuck this n----r!" too, which is acknowledged by the other two occupants at that time.
If all Davis did was bluster and curse, there's no justification in that to shoot him, of course. Particularly when you run the risk of hitting other occupants in the truck.
I wish this was as clear cut as Zimmerman/Travyon. There were injuries, screams, a good eyewitness to the beating, etc. That was an easy call to make. This one is not. But our system is supposed to err on the side of innocence, right? So, if it were up to me solely, knowing what I know, I'd let him off.
