> Ahead of a grand jury's decision on whether to indict a police officer in the killing of Michael Brown, Missouri has both called in the National Guard and diminished the role of the Ferguson Police Department.
Missouri Gov. Jay Nixon declared a state of emergency Monday as a precaution, he said, in the event of unrest or violence.
It's unknown when the grand jury will hand down a decision on whether to indict Ferguson Police Officer Darren Wilson for his fatal shooting of Brown, a teen. Prosecutors have suggested the grand jury would be done deliberating in mid- to late November.
