I agree with both your thoughts. The fact that Wilson appeared at the Grand Jury means he is very confident in his action and the supporting evidence gathered by investigators.

The race hucksters sense this and have been demanding his arrest! You also see the DOJ pivoting to general race relationships on Ferguson away from this specific case.
