Very good news, and I believe the correct decision.
Props to Peterson for standing up for himself, many others would have just paid the fine and moved on(myself included). The fact that his lawyer wasn't present for the grand jury testimony is even more impressive.
Hopefully the officers involved receive some form of discipline, but I doubt it.
