If the chief had asked the DA to charge the officer as soon as things brewed up it may have prevented a bunch of rioting. Any real jury would have acquitted the officer.
The problem with this rout would be the jury. It would be a OJ in reverse jury. Or a real jury finding the officer not guilty would have started Rodney King riots.

I agree that the Grand Jury will vote that crime had been committed and that the DA presented sufficient evidence that Officer Wilson should stand trial.
Remember that the DA in most states is not required to present exculpatory evidence at this point, doesn’t have to present all the evidence he has at this time.
The joker in the deck is that the GJ can directly question the witnesses, none of whom have access to legal representation at this stage. And those questions some times kick the DA in the nuts. Not often but sometimes.
So the DA has a bit of a dilemma IIRC at this point, to call or not call Officer Wilson. He also would not have the advice of his counsel at this time.
While the GJ proceedings are supposed to be secret, I’d bet the odds that before courthouse is emptied for the night some media will have received a selected leak and will run with it.
