From someone who lives a few miles from there, I don't know what the decision will be. However, if the rioters think they can get away with rioting, they will riot regardless.
Did you know that the "protesters" demanded a two day notice before the results of the grand jury were to be released? Why would they want that unless they intend to cause trouble?
Most of the people arrested for causing trouble are actually not only not from Hazelwood, but not even from this area in general. Not only the St. Louis area, but the state of Missouri. People are actually traveling here to from elsewhere to cause trouble in the name of the local populace, and the Hazelwood populace have spoken out against that multiple times.
IMHO, the protesters are living in a fantasy world. they believe person who claims to be an eye witness, however, they ignore four other eye witnesses that all have stories that contradict this one eye witness. Also, with the video of this eye witness, much of what she said is subjective.
The protesters say they want justice. That is a lie, if they wanted justice they would simply let the justice system work. They don't care about justice, what they really want is revenge. The officer in question is guilty in their eyes, no matter the facts.
