Jesus Christ, you don't understand the law!' You have to provide evidence to prove murder or manslaughter If you can't they're acquitted. It doesn't mean it was lawful - where the hell did you get that idea?
Here's just one case where the jury exactly decided the same as in this case. Except in these circumstances it seemed far more likely murder was the intention. But that does not matter because it's not what we suspect or think is more likely, it's what can be proven beyond reasonable doubt in court.

You probably wouldn't have heard of this case because black boys stabbing black boys so it doesn't make national news but this happens all the time.
It is law. Nothing to do with gender.
White primary schooled aged girls being murdered is the top demographic of what the public and society does care about. You really think a jury thought or fuck that little girl, we need to protect the boy? no they didn't. They went by the law.
You'll have to come up with a) evidence where you think the jury was wrong in this case based on actually understanding the law and not just 'i'm upset'
You don't think the prosecution already did all everything to prove it was murder? they did. They just didn't prove enough.
I can also provide you with numerous cases where murder of white girls and women is proven in court and the person found guilty, you just don't pay attention to them so think they're not happening.
