Ferguson MO grand jury being very thorough.

As you might expect, the state grand jury hearing the allegations against a white officer, Darrren Wilson, who shot and killed an unarmed 18 year old African American (Michael Brown), is being nothing but thorough.  Among a couple of the main points from the NYT:
"Routinely, grand juries are virtual rubber stamps for prosecutors, approving the proposed indictments after hearing from a few witnesses and getting the bare outlines of the incriminating evidence. . .
In another highly unusual step, Officer Wilson himself testified before the grand jury in September, for four hours and, per court rules, without a defense lawyer present."   They should be announcing their decision shortly.
