So it's difficult to see how skipping a trial helps him much.
He avoids the risk of decades in prison. That seems pretty helpful.
If there was insufficient evidence to justify holding a trial, there was presumably little chance of his being convicted.
If there is evidence for a potential conviction, then the GJ should have indicted.
All I’m saying is that in his case the grand jury protection has failed, largely because the media did not do their job.
