You clearly do not know what evidence is or are playing a stupid game.
Yes it is evidence.
It doesn't have to be admitted in any court to be evidence.
Lets put it this way? What the heck do you think non-admitted evidence is?
Let me clue you in, it is evidence that the court disallowed to be used in court proceedings. Still evidence though. Duh!
You stated this:
What evidence do you not know about?
He attacked the Officer and pushed him back into his vehicle, went for his gun and injured the Officers face which requiring hospitalization.
After the Officer was able to get out of his vehicle, brown didn't surrender but instead progressed towards (charged) the officer as the Officer fired.
It will be evidence in the investigation, and will remain evidence during the trial.
The Officer's account is also evidence.
It will be evidence in the investigation, and will remain evidence during the trial.
So stop with your silly little game.
