The reason this was an event was because after he was shot the attempted murderer was not arrested. It was not until after the justified public outcry was he arrested. Days transpired and a child fought for his life and no arrest until the public said something.
On the other hand, when a black person commits any crime or someone thinks they might commit crime they are immediately arrested.
The case where the black guy shot his white neighbors an arrest warrant was immediately issued. That is the difference.
One more case when Ahmad Aubrey was murdered the murderers who are now rotting in prison were allowed to live their lives for over 20 days without being arrested.
That is the difference.
