They could (not should) find him guilty, and sentence him to time already served.
As to your assumption that a majority on FR believe DAW is not guilty of the murder:
This is just one of several discussion forums about this, on the internet. The regulars on FR are a "self selected" group, and you are correct in your assumption that the majority believe him to be not guilty.
However the same is not so, on other discussion forums, where on some a majority think DAW is guilty. Few forums equal the attention to every detail, that one finds on FR, which is what all twelve jurors will need to be willing to trudge through, for a Not Guilty verdict.
It remains to be seen, how the jury will decide, and that is WHAT MATTERS MOST. A lot of the FR regulars are certain the verdict SHOULD BE Not Guilty.
My prediction is:
Acquittal, 10% (all twelve jurors with at least Reasonable Doubt)
Conviction, 30% (all twelve jurors with no Reasonable Doubt)
Hung jury, 60% (all twelve jurors cannot agree on either of the above)
FWIW, indicating a high probability for a lot of unhappy FR regulars. Unless Acquitted, Feldman (or the next attorney) will appeal all sorts of things. If a Hung jury, it is anybody's bet, but the odds are for another trial for DAW.
It could drag on for years, raising the (unlikely) discovery of the "real killer" or a plea bargain by DAW. Remember those pesky motions by Feldman, sealed until appeal ('...if I did it, I was drunk...')? Who knows? Reality can have a hard bite to it.
I believe DAW is probably guilty, but it has NOT been proven to me, beyond a reasonable doubt. (I could change my mind, based on remaining arguments and closing statements.)
