Did anyone seriously think the prosecutor would bring charges? This is Seattle after all, where the written law means almost nothing especially when the fate of a lefty is involved.
Not "almost nothing" but "absolutely nothing". Remember that this is the state in which over 20,000 violent criminals were released early supposedly by "mistake" which had a savings of tens of millions of dollars for the state, but which resulted in an explosion of violent crime.
The government is not our friend - in most situations, the government is the enemy of the People. Government exists of the government by the government and for the government. From their POV, the People deserve absolutely nothing but contempt and only enough lip service to get them to do whatever the government wants them to do.
