It's easy to not know the whole story and just make assumptions. The case can easily go either way. If Yang gets a good enough lawyer, he has a self-defense case. If not, the DA will rip him apart and he will be labeled a murder.
The shooting happened, there's no denying that. And it was Yang who shot Lee, no disputing that as well. But the question is why did Yang shot Lee.... That will be the case.
You have to ask yourself, why was Yang carrying. To look cool,... maybe, possibly. Or maybe he was carrying because just days ago, his house was shot at. House still boarded up and threats was made on him and his family's life.
Witness said that all they saw were 4 guys walking up to another. Well, it wasn't 4 stranger nor friends walking up to another.
..... case here. House just got shot at, life was threatened. Enemy called 3 other guys and is now walking towards you. What is your state of mind then. What is Yang's State of Mind. He has his wife and kid to think about as well. What is going through his mind. Was it pride,... or was it do or die.
If it was pride, why didn't he grab his gun and step up to the 4 guys. Indeed it was 4 guys, but i'm sure if it was pride, he'd have enough bullets for 4. But if it was do or die,... well, we've all read the end result.
