I was not challenging the result of the decision made, only saying that different racial compositions of the jury may have led to differing results.
Which, in essence does challenge the decision inferring that a different racial component would lead to a different outcome which would mean the system is flawed.
It is a very open ended and reasonable piece of speculation on my part...
And that is exactly what is it...just as you say...pure speculation.
I think that latter premise is not one we can reasonably assume, certainly for this particular case.
Bltiz, you are not a US citizen and are not as familiar with the legal system here, particularly Grand Juries. The Grand Jury system was designed to avoid the very things you raise.
As stated, the Grand Jury is very heavily weighted towards the prosecution. Those are the facts and n speculation involved. Judge's instructions are always very clear.
The absolute most likely circumstance in this case is that the evidence simply could not support at all any indictment.
At a normal trial, the threshold for conviction would have been even higher.
Certainly by making the statements you are making, that the racial component "could," play a part in rendering a different conclusion, you are clearly questioning the outcome, and thereby, the overall system.
Those people saw the evidence we did not. They made a ruling when faced with five different charges...and in an environment where a No Bill was clearly going to lead to trouble. They no billed it.
We can all look at the evidence now...it has been released (which itself was unusual).
Anyhow...IMHO, it is best in such a case, not to use speculation like this.
