From news reports on MSNBC and other outlets, the city is prepping for the worse that could happen if Wilson is not indicted; but I did read on
www.comcast.net yesterday that the Grand Jury did also hear testimony from the coroner retained by Mr. Brown's parents for their own autopsy results.
IMO: If no indictment is issued, then I hope that all sides keep the peace but after the occurrences over the last several months (which have ebbed down somewhat) and Mr. Brown's parents spoke at the U.N., the whole world is watching Ferguson, MO.
